Um, I did mention that I used the noise filter, and I also mentioned that I wanted to move away from using the noise filter in photoshop but I don't know how to do it and have it look somewhat decent. Like I said:
However, I'm not sure how to go about shading a roof without it looking flat and ugly. Textures are beyond me.
Replace roof with other things.
Obviously, I'm asking for help with all of this. Once again, I'm new and the only pixel technique that I'm pretty much aware of is dithering and that's about it. Also, I can point out a majority of the objects on my tileset that were almost completely to completely pixeled (the lightpost, the bench, the grey road, the bricks on the building, the cobblestone).
Also, even with the stuff that I did use a filter on, I drew the outline, and put down basic colors and shading. I read the rules and I don't see anything wrong with this because I think I can benefit from "pixel-level critique" despite a filter being used.
