Love the design! This is really beautiful and the eyes are wonderful!
I don't mean to be a critic and I admit I don't know much, but aren't ghouls supposed to have rotting flesh?
(I could be mixing them up with Zombies, but as far as my knowledge goes ghouls are half ghosts half zombies.)
In the arabian story the ghoul is a Djiin not an undead
I have done so to improve the quality of my drawings (and I assure you that even I still have long way to go)
Always remember: never overestimate your own and not have to ever be convinced to have made one thing perfectly. The good artist is the one who gives himself a pat on the shoulder and says, "good, but could do better, next time you need to do more," or else you will not ever grow up.
At least for me it is.
