@Decroded: I know; that was actually a screenshot. I was testing it out to see how easy it was to map with. I resized it this time.
@Corinthian Baby: I see what you mean. I've made some palette adjustments and did a ton of cleanup. Hope it looks better now! I like the idea of the shadow, but I may want to use this wall tile with other floor tiles. I'll make some shadow variations when I'm done with everything else.
@Dusty: Wow, your lighting looks SO much better than what I did. Thanks; that was a big help! I like what you did with subsequent blocks being lit too, but I think it might be too annoying to tile with. I'll look into it when I've got everything else straightened out.
@Jad: Is this better?
Uh, I think that gray fading light color might be too purple. I'll keep messing with it. I think the floor palette is also not still right, so I'll mess with that more too. Also, as a note, if the character's skin looks too whitish, she's an albino.
Thanks for the feedback, everyone!
