Better than anything ill ever be able to do heh..
I dont know if you appreciate it or not, but heres some critique
Very nicely done. Shading seems good. The head sizes bothers me a little bit, though i cant see if its size whats doing it. Coloring seems nice. The red one's left leg seems... Idk.. Broken? Andmaybe a bit feeble
Also, Try adult tag. Not too explicit for mature.. But theres still nudity (and not for anatomical reasons)

You may hide this comment after ya read it if it bugs you. Have a good day and continue progress towards perfection and epicness ;)

aww shucks it's all practice, i'm sure you could do (and outdo) it with enough practice i'm just a hobbyist

Thank you for your feedback, nothing to hide here as it's good old constructive criticism.
I can see what you mean about the proportions, and the pose/stance may not seem entirely right x.x i was working from a reference photo the person that commissioned sent and wanted to get the general pose similar (as best i could, at least) to it, but it seems to have fallen short.
I hope that i can do better in the future, specially considering people are entrusting me their ideas x.x, if 'i'm not there yet', i'd like to improve, both for myself & for them to get a better finished result...
I tried my hardest for a few years with certain material ("andrew loomis" books & some "glenn vilppu" workshop dvds) but not all of it sinks in, i feel ^^' it is complicated for me, but i try.

Thanks for commenting thoughtully on my pic & have a great day
