Woah!!! That must be hard!
I'm really sorry, but I don't know that I want other people to use my sprite base. :( I made my own because I wanted my character sprites to stand out from other RPG Maker games and have a unique look. If you want to get started with pixel art, this tutorial is really helpful! I'm sure there are also some freely available sprite bases out there for RPG Maker that are different from the default ones provided. Good luck!!
