Hey there fellow bronies! I was wondering if I could get some help on my Pinkie Pie cosplay. I attended my first con as Pinkie Pie back in January with a pretty sad costume, and not a lot of people recognized who I was actually supposed to be. This was last year's idea, which was very bland. I have 2 sketches but I was wondering which one would be better? Or what I could add to them as well? Any help or advice would be very appreciated!!
