On the contrary: it is not uneven enough!
Please, this was just a test, and I don't intend to make this into a movie. If I was to, I'd need to rework all parts. I'm not really good in this style which seems to come naturally to some other artists, like the sample Gnaws gave here:

What I would do, though:
- add textures where necessary
- don't use gradients, instead stack uniformly coloured items so they give a similar impression
- separate outlines and coloured shapes even more (think "101 Dalmatians",

- definitely not do any enforced 3D rotations, except where the story needs them
- don't do any realistic shadows.
