Yes it is Pele's sprite. I just wanted to add detail for fun, I realize that's not good, so I'll draw my own, which is actually indicated in the posts above.
-Also there was no filter, there was layering, which is entirely different, but I get your point. This was an idea, I'm not going to keep at it. I'm going to draw some Doom2RPG sprites, that can pass as higher res. I'll do that later, as I'm already working on something, but it Will be done, at least attempted.

It looks better with the HD mode, but if you work hard in the high-res you can make the monster much more better.

Yeah, indeed the HD one looks better. I know with hard work detail adding could look good, but it would take a lifetime. Same with drawing those Doom2RPG sprites, so I'm not doing it now. Instead, I'm trying a process similar to making sprites HD, but with more detail. My Baron of Hell looks pretty good so far, I'll post it when I'm done -All i need is the mouth now, the mouth is really hard to recreate...
