Mario
Well cant get any better with "MARIO" and I like the newgrounds themed backround well the old one anyways, but as for that backround I would suggest adding some either shine or texture in the backround colors, as for mario he looks pretty well done nice shine nice form of the lines and you made a good renditton of classic mario that we all have come to love so I did enjoy it for its artistic value.
