Sorry, my response below was a little mean spirited. But I was surprised to find a comment like that. I don't know you, you don't know me. There's a "critique" button one can place on their Deviant Art entries if someone is interested in receiving critical feedback. You'll notice I didn't include that in my art post. So what you've done with your comment is the equivalent to a stranger walking up to you in the street and them saying something like, "Hey, you you could lose 20 pounds. You're fat."
It's just rude. So, I apologize for my comment below but I think the nose is fine. I have a good eye and I'm very self critical. I see a stray line across the tip of the nose if that's what you're referring to... Regardless, one shouldn't throw stones if you live in a glass house. Anyway, just thought I'd explain myself.
