Its really good, the left side of the face didnt go so well, i agree the black marker would defintly make it stand out against the background, anyway when i draw i do notice a year later im alot better and you just keep getting better, just wait in a few years you'll draw that wolf with ease! For youre age im quite impressed. I give it 9/10, just the left side of the snout and the left eye thats making it look odd to people it seems. Keep drawing =]
