Well first off, welcome back to the crew
...
Second, I'm not much of a pixel artist, but if it's one thing I know, it's refreshing the memory. Unless you never got cold feet, I suggest messing around with stuff as far as the art department goes and see what you remember. Improve on previous error's (if any), and once you got stuff down, share what you have and just do it for fun, and keep it going!
As for me, i've just been innovating Ikemen engine and been working on my Mugen Online project (which is available if you want to check it out)... But yeah, i feel ya. I just technically finished high school and on my way to college.
hope any of this made sense or helps ya out...
