Really fun, and an explosively colourful! You've got some nice design work on your characters as well.
The problem is its very cluttered and disorganised. I get the impression the stuff in the background is thrown together; the wing and speaker look out of place.
There's not really much thought behind the colour, either. The girl is wearing reddish browns, yet the guy is white, yellow and blue. Coupled with the random colours in the background, everything just clashes against each other.
Keep up the good work, though.
