Well, ok, here's one. I don't have the original blob. When I looked at it, I thought "Is that a dwarf mooning me?" Which I hereby present to you as the dwarven plumber:
P.S. I use Carb Code color shader utility to help me with the shading!
Oh my, this was unexpected indeed XD Really fun though and like you said never would have thought to draw a dwarven plumber! Gives me ideas about what a game might look like with this character, fighting off broken pipes or rats and leveling up skills to go deeper in to the dark sewers.
Oh also a small tip for better visibility when posting btw! When you exporting via file>export setting it to 300-400% makes a larger image but keeps the pixel goodness as it scales everything up!
Thanks for sharing this!
