Redline as in the drink? mmm... being ADHD that stuff has little to no affect on me. As far as the picture is concerned the female is very well done, The males arm seems to be a bit off (the one going behind) Tho i feel kinda hypocritical seeing as how none of my work even come close to comparing with yours. but i thought i'd give it a go.

By Redline do you mean take the art and do a little doodling over top to show where things could possibly use improvements? I'd be happy to help.

Ahhh... I love to see large rave pictures, I can't wait to see this one done... :D

You've got a lovely sense of movement going here and a great start for the anatomy. As far as an honest critique, mostly the arm reaching behind the male figure there.. just lowering it some would be a start, it's much too high for being able to reach that far. Maybe it's a bit too long in that respect, as well. I'd lower it and shorten it just a bit. I'm afraid I have no actual time for an actual redline :( And I can't really tell what's going on in the mouth region of the female figure o_O But other than that, you seem to have a great thing started :D

Down! That's the one direction I hadn't thought of, I'd been playing with Rhari's length suggestion a bit, but I think moving it down will make all teh difference. Thanks!

To be honest, here, all of this has such great anatomy.

I can't see anything wrong. :o
