Eh, I gave it a try. I just changed a few minor things, and changed the color to GB style. Unfortunately though, I do not know of the person who made the original Gohma. I don't think it's too bad though. I made a little mockup as well. I think it looks a little bit too big though to fit with GB style...
By just recoloring an alttp style Ghoma with GB colors doesn't make it an GB style Ghoma.
Yeah, I was aware of that, which is also why I mentioned that I Thought it's too big to fit with GB style. However, just as a learning experience, what exactly makes a GB sprite a GB sprite other than size and color?
