Nice start, cute lil wabbit, everyone loves platformers, and mockups
. To my mind, the simplest way to unify the two scenes at the moment would be to afford the first a background and, as blu said; get rid of the highlights in the second.
A pet peeve of mine is repetitive ground tiles so I jumped in and demonstrated how some variations could look, as well generally simplifying and clarifying things, going bluer. I would also watch out that some of your little bg elements (flowers, blocks etc.) don't get lost in such a large frame. Could probably still do with a little more contrast.
