okay, thanks for your criticism, neico.
I'll try "to ease up on hand smudging" (like you said it - I hope I got it right, I had to look up these words...^^)
your drawing looks great - It would be nice to see a bigger version
I think I know what you mean, the shadows in your image look much more authentic. they are more grainy and not that smooth as the ones in my images, what makes them look somehow unrealistic and undetailed...
