Here are a few tiles I drew.
I was practicing a new way of making tiles. Basically, I do a tile by attacking it a corner at a time. I do the top-left tile, then I make a top-right tile by sandwiching it between two top-lefts, make the bottom-left by sandwiching between top-lefts, and make the bottom-right by sandwiching between the bottom-left and top-right. Then I just went through and gradually adjusted things.
I think it turned out well, especially for my grass. The sand there is a little weird because it's supposed to be checkerboard tiled, but it's okayish.
Here's a picture showing rough progress of the grass artwork along with palette fussiness:
EDIT: This was originally an art dump, and I had a really poorly drawn flaming mushroom and a bee, which I thought was good when I was sleep deprived. Yeeaaaah, I got rid of that.
Instead, just give me your feedback on my tiles!
