Well, took a break from the caves I was working on...figured I'd get some practice doing random pixel art before I worked on anything I planned on actually using in a game, hahah. So now I'm working on an RPG tile set, with the goal of getting a little town next to the ocean finished. Grass, dirt, and trees came out okay, I think, but I'm having a lot of trouble on the house. I must have put about four hours worth of work into it so far (I keep on revising, then starting over), and it keeps on looking like crap. The main problem I'm having with it is what to do with the empty space on the walls between the boards. They're supposed to be made of a smoothish stucco-like material, but I can't get them to look interesting at all, no matter what I try, it seems. My second biggest problem is the wooden planks. They're not looking so hot, either. The roof, like the walls and the boards, also looks like crap, but it's just a placeholder. I think with some work, I'll be able to figure out the roof myself.

So...yeah! Any help would be great. I'm stumped!
Ah, also...I'm thinking about pushing the palette more towards something like this for certain situations, if I ever do end up using these sprites in a game down the road:

Is the tree more appealing in this sort of blue light, or under the natural sunlight in the first mockup, do you think? I think it looks nice, but if a whole game was tinted blue like this, it'd probably tire me out. So I was thinking it'd be nice to use in deep forests and stuff like that, using the regular palette for most of the game.
Edit: Ah, for full disclosure: Referenced Seiken Densetu 3/pixel art tutorial for the dirt and grass. Referenced Seiken Densetsu 2 for the general shape/height of the tree, along with an old painting of mine for the colors/leaves. Building used a thousand references, but none of them helped. XD
