Can I say how great this looks? Really, the minimal approach can be amazing if done correctly, and this is one such example of the minimalistic approach. Great work; it really put a smile on my face!
However, there is one problem I have with this. Her mane and tail lack that cotton candy thickness that she usually has. It looks really off, seeing how she's Pinkie Pie. The 'pony-nality' just shouts charisma and magnetism, but the mane and tail here says otherwise. But, other than that, there are no complaints. Again, great job!
