Here's a comparison between old and new. When I made Unipey the Navi(lBlue one)

it was mostly on the fly, and although I made a pattern I didn't adhere to it strictly, and didn't note amendments made at the last minute.
I worked on Unipey during the 2nd and 3rd term of my first year of university. In the past my commissions have usually taken roughly 2 months start to finish, but with my current revamp of my pattern library I hope to be able to make basic humanoid characters within a couple of days...maybe even hours :D
