thank you for the suggestions. for the first batch, the orange tiles were 16x16 and the purple one was 32x32. for the newer ones, they were initially 16x16, but after an accident i resorted to making them all 16x15. i'm curious in attempting your last two suggestions, the one referring to overall highlights, and the one about implying separation without outline. I'll try finding some examples to look at, but you you explain why their should be overall highlight/shadow difference since they're all on the same flat plane? i'll try working on the outline though. Also, of the four styles I attempted, which would you recommend I continue working on?
