If you need additional art, I can do 2D character concept art and illustration if you still need help with that, and I would like to get better at environments too, should the opportunity present itself, but it's not my forte. I also have a graphic design background so I can help with UI elements (at least the visuals). My life should be getting slightly less hectic in April, so I expect to be able to dedicate a couple hours a day to the project.
Update: I forgot to mention I personally like RPGs, especially JRPGs, but I enjoy a lot of other genres as well and I'd be up for working in any of them.
