This is quite a nice image, way better than your other works, creativity wise.
Next time you better not choose a photo background (those are "against the rules" here) and try cleaning up the edges when cutting out the pictures, a light smudge might help.

Very nice! There's a lot of improvement in this image. I can't wai to see you improve further! Don't let anything or anyone stop you from becoming a better artist :]

Yay! Something, new atlast!
BTW, good job, on it!
