No offense intended, but make this a smaller file. There's no reason it needs to be this big and most people, myself included, do not want to wait for a 1 mb picture to load. The colors look nice from the thumbnail, but I guarantee you that the enormous filesize is turning people off.

Now that the picture's loaded, you do have nice shading here, and good motion and expression in the picture. But do try to decrease the filesize.
