Photo Manips: Skin Touch Ups.

OK well recently ive learnt to touch up and hide skin imperfections with photoshop. Just wanted some comments and such. Heres an example I did using an extreme photo that I found on the net.Left side is my work, right side is original

it is slightly noticeable that you've touched it up from just looking at the left side.

wow, how'd you do it?
Nice work anyway, :D
