So I decided to start working on the OW sprites since that's the biggest sprite sheet due to the animations and poses sans has. At first I basically refined my last ow sans design, but I just ended up disliking the eyes a lot. So instead of starting from scratch, I decided to sketch sans and do a little bit of studying to understand how he's drawn. Which you can see in the next two images. With the new knowledge I had I started making the new design and I like it much more than the old design.

I will start making the walking animations and poses soon.
