May be a little difficult redrawing them to make all them bigger, I just wouldn’t have the time to do that I’m afraid, plus they are drawn to a set of criteria I have laid out for my RPG Series. Perhaps you could scale them up to make them bigger resizing the 16x24 size to 32x48, they might be to big for what you need though? Or maybe you could set up a ‘camera view’ in your software that may better fit your game art?
Il be working on lots of things throughout the year and eventually I’m sure you will be able to build your own little city with the combination of tile sets, vehicles, and other environments that will become available in the future. its a slow process but il get there eventually.:)
