The front of the skin is a spider I based on a game called RetroMMO.

RetroMMO is an online role-playing game in the early stages of development. It pairs the core game mechanics of classics such as Dragon Quest and Final Fantasy with the format of a modern MMO.

I play the game a lot and it's just really cool, so check it out if you're interested :))

Also used the palette from the game for both arts
