I really like the pose you gave to Pinkie Pie in this picture. It's enough to make me automatically picture her going into another over-cheerful monologue like she always does from time-to-time. I also want to point out there's some details about this picture that I think came out really well. The bluish reflection coming off the crystal platform is very subtle, but it adds nicely to the picture especially when adding to the curvature and depth of their tails in my opinion. The sheen on their manes also seems new to me, and I think it looks really nice on your artwork. To me these two look like they just got off the Equestrian station to meet the con-goers. I hope this sells well for you at the convention.
