You made a critique to me time ago so now i want to make you one. You don't know why that's your most popular deviant, I think it's something related about the atmosphere and the design of the character, hidding for exemple his eyes, this little teeth, his long nails, the usage of a few colors helps to create an dark atmosphere. In my opinion the design it's excelent, and probably the only think i would change about it, it's to show background a little bit more far from the the character, but in any way like you have done it thelps with the atmosphere. Some parts of the body could be a little bit more shadded to. But in any case, it's looking very great, congrats for this
This is cool in a weird creepy sort of way. And yeah, I'm in the same boat, my most popular deviation has -459- faves at the moment (D:!!), and I have NO idea why. I did it in like, 30 minutes, late one night, and it isn't even that good.
I don't understand people sometimes. xD But this is awesome. /rant
