wah super cool wall. digi charat seems to have all the perfect characters and scans for walls.
the image doesn't look very high quality. there's some grainy areas and the colours just look a little bland. i dont know if you made the clouds yourself or used a stock image but they look pretty awesome. the bubbles weren't too much. just maybe few of them. and the grass looks pretty poor compared to the rest of the wall.
still, nice job.
