Just finished this one today and got the thumbs up from the client.
runei The character's name is Oksana and the machine gun she's holding is a Russian Kord link One biggest challenges in this piece rendering the ammunition and the ammo belt.
Which brings up a question for my viewers. I usually associate most post WWII Russian military firearms as chambering steel cartridges, but every example I could find of 12.7x 108mm showed what looked like brass cartridge casings? That seemed odd because 7.62x 54R is steel and the 14.5mm KPV casings look like lacquered steel. Does anyone have any information about this?
The piece is rendered in my usually mixture or colored pencil, marker pen, gouache, and technical pen. The working surface is vellum Bristol board.

I did a little poking around on the 12.7 x 108 and found the following:
Re 12.7x108mm:
DESCRIPTION: The case is rimless and bottle-necked, of
brass or varnished steel and Berdan primed. The standard
bullet is a non-streamlined armour-piercing/incendiary
pattern with a steel core inside a steel jacket with
gilding metal envelope. The core is shorter than the jacket
and the space at the front filled with incendiary
composition.
SPECIFICATIONS: AP-I B32 Round length: 146.80 mm Case
length: 105.90 mm Rim diameter: 21.60 mm Bullet diameter:
12.95 mm Bullet weight: 48.28 g Muzzle velocity: 840 m/s
Muzzle energy: 15,570 J
This statement calls out either/or as available in the caliber.
I'm not sure about the frequency of one type of case or another though, so who knows on that point, nor if the belted version may have had preference for one or the other case material.
Great artwork as usual, and always interesting to see what gun one of your girls is toting, every time I see one of these!

And the various pictures of individual 12.7x108 cartridges all show what look to be brass casings: http://gunsru.ru/rg_patron_12_7x107_eng.html -- even the cutaways look like brass on the interior, so it's not just a thin layer over steel. Admittedly, cartridge encyclopedias generally only show one of any given cartridge, picked as a 'representative' example, it may not represent the majority of manufacture.
A closeup shot of the receiver and a short section of belt with dummy cartridges can be found at https://www.flickr.com/photos/angad84/7073211087
This page -- http://survinat.com/2014/08/threade.....rmation-about/ -- has more pictures of the cartridge, and as a bonus has pictures of the packages that the cartridges are shipped in, showing that at least for current production they use brass cartridges.

Simply awesome 
baroncoon! As always, I'm so very impressed with the details you imbue each character with—:runei:'s lovely Oksana is no exception! I still argue you do the best hands and feet, especially among traditional artists. I love how you capture the shape of her wrists, her powerful biceps, well-proportioned thighs, and toned calves. Again, the ankle and foot anatomy are detailed and superb! Her abdominal and lower belly looks ... inviting, shall I say?
As for the rifle, it is quite a lovely "character," as well. I love seeing rare and odd-looking infantry and crew-served weapons, and the KORD certainly has its own unique flair. I can't imagine how long it took to draw that ammo belt! For those not familiar with the cartridge (12.7x108mm; 12.7 SOVIET/RUS), it is basically the Soviet/Russian version of the U.S. .50 BMG (12.7x99mm; 12.7 NATO) anti-materiél rifle (AMR) ordnance.
The Soviets began researching large-caliber machine gun ordnance in 1927, almost a decade after Germany's introduction of the "tank-busting" 13x64mm Mauser (.51 cal) in 1918, and six years after Browning's development of the 12.7x99mm (.50 cal) Browning Machine Gun round for the U.S. Army. By early 1930, Tula Cartridge Works had perfected the new cartridge with by increasing the case length to 108mm, making the new round slightly more powerful (increasing from 270 gr to 293 gr smokeless powder) than its American counterpart, at a slight expense in accuracy.
Initial production of this new round, designated the B-30 ("Ball, 1930"), was at Tula, and later, Ulyanovsk Cartridge Works. This became the primary armor-piercing (AP) round issued to the Red Army, able to penetrate 20 mm (0.78 in) of steel plate at a range of 1000 m (3280 ft). In 1932, an armor-piercing incendiary (API) version was developed at Ulyanovsk (with an improved effective range of 1500 m), designated the B-32, which has remained the primary Russian AMR, aircrew, and anti-aircraft artillery (AAA) cartridge for the last 80-plus years. In addition, 12 other variants of the cartridge have been developed, including more powerful API, tracer, high-explosive, fuzed AAA, sniper, and blank training rounds. Regardless of the variety, all 12.7 RUS cases manufactured in Russia, China, Iran, Pakistan, and India are made from brass, though cartridges made in other nations (especially those in Africa) have been known to use questionable amounts of brass-jacketed steel casing.
