Myu, look, I can comment to you here without my computer crashing!
Something about depression...it seems to fuel creativity, it does...so at least one good thing comes of it. Hm...something about drawing dark entities...of course, you don't find many people drawing happy pink bunnies when they're sad...unless a dark entity is eating said happy pink bunny...
I'm forced to make my general comment about arms in regards to Isis...elbow should reach the hip, fingers should just barely brush the knees. That said, there's very nice attention paid to detail in regards to her outfit. And the folds on Yami no Malik's cape give it a lot of depth.
...but where's Rishid? XD
D= You should never lose confidence in your art!! You are very talented from what I've seen and never stop drawing! And remember that even if you aren't satisfied with your art now, which you should be since you're so good^_^, if you keep practicing you'll get much better. The guy in front is Merik? Anyways, his cape looks really awesome and the way you shaded it looks great!
