I am planning to make a game, but I really desire that the game is 100% custom, and so I am trying to make the graphics for it. However, I'm not really an expert on making tilesets, and before I continue churning out more shapes in the same style, I'd like to receive some feedback on if I'm making them correctly. Overall, I'm basing them off of Pokemon.
