Good concept, poor execution,
I'm liking the idea and overall imagery, but the actual quality of the art work and craftsmanship falls short.
Originality and zaniness are always applauded in my book, but this could be so much stronger if the material was handled better.
The paint feels thin and washed out, not in a good way. The details are muddy, even from a distance. With paint its acceptable for details to disappear when the piece is viewed up close, but this one loses them from the first glance and never gets them back.
Colors seem a bit arbitrary as well. Things are colored based solely on their actual color instead of a perceived color, where light, air and reflective qualities would be playing a part. To paint a t-rex green, the sky blue, a tuxedo black, etc. is just basic. Each should have a tiny bit of the others mixed into them for unification purposes in a stronger piece.
Valiant effort, but needs improving.
