I find the face messy now. You're both highlighting and outlining the nose, I think it's better to just pick one. I think the best of all solutions to representing the nose is a plain 2x2 highlight, as outlining it will either give him cat lips/mustache or a black eye. Try out variations of length and position of the block. I found that just by removing the nose outline you have now is probably the most readable position. Also, concerning the color of it, even though it's a highlight I think that it could use more saturation, until it's a light pink.
