Ok so here is my feedback
+1 for crates and the wood is ok too
metal seems ok and i definetelly like your snow
I dont like most of your grass texturess especially grass1_2, grass1_3,grass1_4,grass1_7 - they look ok outside the game but ingame it doesnt look that good
I like half of your rock textures but rock1_2,rock4_2 is too dark for me and also it looks like creased papper painted to grey
