First of them is a game character I'm developing based on this concept (not mine!). Obviously it's still a WIP and it's not a exact copy of the drawing. I know the rendering looks like shit but I hope you can at least get the idea.

The next one is an illustration I did just for the lulz but I'm planning on showing it as part of my portifolio tomorrow in a job interview, depending on what you think of it! (NSFW)

Thanks!
