Shipping Level: I see you fixed the perspective, these look cool now. BUT! you may think about adding a little more vibrancy to the crates. They look as if just brighter/darker hues of the same color were used. The shadowy part could have a tint of blue and the lit part--yellow/orange. Just a suggestion.
Snowy Level: These tiles doesn't really blend well vertically.
Sunny Level: I think I liked the previous version better, it was simpler and less eye-tiring. The lower part of the tile, however, could be darker (maybe even more than in the second variant) to make illusion of a 3D shape, i.e. long blades of grass.
This is gonna be a nice-looking game, no doubt
