I'm currently designing many, many ponies for a RP-Setting... and with many, I mean MANY. I just like to have visuals for all the characters.
This is a girl I recently finished because I really, really wanted a red unicorn mage among the characters. Alicorn version just because I can to keep my options open.
Yes, I know the cutie mark is a little complex in comparison, but... I wanted something abstract for a (short tempered) magical scholar.

I think I have about 6 different Mane colorations saved, the major decision was between the version you see here and one without the purple streak, containing only the bright colors.
Version without purple streak - http://sta.sh/0194ypu72ruv on the left
Version without orange - http://sta.sh/01hwt2rejnig
Fullcolor version - http://sta.sh/0265js434zt6
The darker red parts of the alicorn version turn more purple the more magic she uses.

So... what do you think? I'd love some constructive criticism and suggestions, just please be gentle and don't destroy my feeble self-confidence :'D
