I agree that there is something masculine about Pepper in this; rather than being one specific thing, I think it is a series of small things which combine to make her look just a little manly. I think the shape of the face is the biggest part - perhaps rounding out the cheeks would help with that in the future.
Regardless of this, I still like it. I don't think it makes the drawing bad, just different.
Is your comment meant to be constructive? Your comment is presumptuous and a bit insulting, rather than constructive. It's obvious that practicing more would be ideal, but I don't have the time nor the motivation to practice more.
What can we do? deviantArt is full of talentless hacks like me, and arrogant assholes like you.
