The hardest parts of drawing kissing, back when I drew at all, were threefold:

1) Dynamism without too much exaggeration. Kisses needed to suggest motion, leaning, imbalance, interesting 'action lines' -- without being overly dynamic, overly kinetic. Berne Hogarth methods were a spice of great granularity, and a sprinkle too much kineticism turned a kiss into bad comedy.
2) It's really, really hard to convey artistically-recognizable emotions, in a place where people often have a very passive, resting face. (Hand placement does a *lot* of emoting, as does leaning, twisting, and shoulder posture...)
3) The longer the muzzle, the harder it becomes to model the kiss like an identifiable human kiss.

You've done a gorgeous job here. As a once-artist, I am damned impressed!

First off I really appreciate you feedback here even if I feel 'oh man, I has the dumbs and don't know what to say in response!' sometimes.

Kissing o me has always been an interesting drawing challenge, but anthros bring that up to eleven, so I am glad that my practice of this has had positive results so far.

Expressionism and emotions is something I really do want to focus on more; I do really love doing pin-ups, but they don't offer a lot of opportunity in that area, so been thinking on moving to comic and interaction stuff more.

Absolutely beautiful.

daawwww

Very nice! :)

Sweet, I need to practice drawing my characters kissing too.

It really does help!

well practice gives you good results.

That is my hope!

Always gotta love it when a piece shows feelings and romance between characters

Yeah, me too, something I need to practice on.

I here ya on the "drawing people kissing can be a pain in the arse" thing though....pretty great job here.

Yeah, it is somewhat of a challenge with people, with anthros, it becomes even more of one.
