My sister and I have been wanting to colaborate together for some time now, when we both have free time we will do so, probably animal and human related, I will mainly focus on the animal and her the human, but both of us will work together to create a piece, hopefully with background too, and they will be A3 in size.
My sister can be found here> http://www.furaffinity.net/user/anime-maniax/ She is 16 and will most likely become a better artist than me!
These two pieces are just two of ours photoshopped together so not a colab, this pic is merely an intro.
And yes that is rainbow dash to the left and just a random griffin chick my sis drew the thr right, could be thought of as Gild/Hilda the griffin in MLP though!
