Greetings everyone. My friend and I have started work on a simple defense game, and I've whipped up some tiles for the game, and now I'd like to hear some advice on how exactly to improve them. I'm aware that the tree is somewhat messy. The pink background is supposed to indicate that the tile will have a transparent background.

I'm not sure how to go about drawing the dwarf in a sideways view. I did some experimental tries, but hm, I removed those, as they were quite terrible.

And the slope-up-the-hill tile could be improved, I know.

Anywho, I look forward to your comments and advice.
