Low res City

Pixel place i build using Blender and Aseprite. My idea is to promete my band gemini (where i play bass) with this artWork and to practise my texturing. Everything in the scene is texture with a 256x256 image except for the gemini´s poster that is an other image of 64x84 pixels. Really is this a very optimized scene, really dreaming to make a mobile game with this style.
