I decided to take a brief break this evening and try Colors! 3D again.
I had used this application previously for quite a few works. Being an application on the 3DS and non-Windows tablets only makes it somewhat difficult for me to stream art from, but I am sincerely considering getting a 3DS capture card to alleviate that issue.
Coincidentally, the snaggletooth here is colored in the final version, but this upload predates it slightly. Colors! isn’t especially amenable to reuploading an existing illustration, so I’ve decided to leave it be.
