No idea what category to put this in.... ._.
And dA won't let me put = and P together without it making this face: So you're going to have to take away the spaces for the 'Personality' and 'Physical and Health Info' categories >-<
Here's a pretty detailed character bio fill-out sheet that I made and wanted to share. I hope you can find it useful!
I'll probably update this every once in a while when I feel something needs to be added/edited.
(PS: About that 'Mutations' slot: That is for some physical appearance traits that aren't just markings. Things like scales, special tail types, unusual ear size/shape, etc. go here.
