This is really really good, I love it. I like the way you combine the wood texture with the image, good job!! the colors are great too. ^_^

I like the idea with the wood. It looks great even with that vertical line cutting right through the eye of the character... About the multiple lines that unite the two characters... I think most of them are a bit too straight and too chaotic, some turn too sudden, creating angles; maybe less lines [and if the ones that remained were more curved] would have improved the aspect. Very nice colors. I'm still not sure about the the two post-it notes... I can't make a connection between them and the rest of the image, it's like they don't fit. Also, personally, I would have liked the bottom character to be slightly higher placed, and maybe just a li'l bit to the right; but I'm not quite sure if that would have looked ok. Nevertheless, great wallpaper and the way the light falls on the face of the character, it brings him into attention and emphasises his emotion and facial expression. keep up the good work ;)
