Everyone is entitled to their opinion. Personally I dislike pony cosplayers doing strictly human interpretations. I think it pulls away from the fact they are in fact ponies. I like the combination of features because it credits it's source while allowing for creativity in the design of the costume itself. Overdone? Absolutely. But, overdone for a reason.
Thank you very kindly! Any time an image is in "Cosplay" gallery, it was made by me. My "photography" and "cosplay commissions" galleries are for work that isn't modeled by me ^_^
But i think it would look better without the wings and ears (but it still looks awesome!)
