Hey, guys! I really appreciate all the great feedback, but I've been busy the past few days, and with the way I have this set up, retooling things is a little cumbersome. I want to do more than just a palette change, so I'll probably post an updated version sometime in the next couple days.
Dusty and Elk's edits are definitely a lot more readable than my version, but I think they might be a little bright for the atmosphere I was going for. I wanted something sort of dark and moody (so with that in mind, the sky panorama doesn't really belong with this particular tileset, but I felt the need to include it since I had it). I think it's the grass that's bothering me more than anything, but it's much easier to see what's going on when it's light. Maybe I can add a dark accent grass or something and use a lighter one for the main tile.
ndchristie, thanks, I'll try that when I go back to it.
Ben2theEdge, that's actually a really good tip that hadn't occurred to me. Looking at screenshots from professional games, I see they do this, and I just didn't notice. I'll keep that in mind when I'm revisiting things.
Gil, here's an animated version:
A number of the poses are somewhat unrefined because I intend to draw them individually for each character. As for the walking animations, they're kind of weird because they're three frames and the middle one has to double as an idle pose. Well, there are four on the sheet, and the first one is both the idle pose and one of the intermediary poses for the walking, and I'm having a hard time visualizing how that could work in a way other than what I did. The program I'm working with is limiting. I
may be able to change it, but keeping it as it is also means I have a lot less spriting to do, which is a consideration.
