Manehattan Project 3

Don't feel bad that I didn't mark anything 5--to me, five stars means it can't be improved in ANY way.

Your artwork is very good, a solid match for the show's style, and visually attractive to be sure. You definitely seem to have character personalities down, and the expressiveness of each character is fantastic. While the gradient doesn't work for me in the text panels (such as Apple Bloom in the fourth panel), it doesn't make it difficult to read. I simply don't feel that text panels are a great place for multiple colors. The text should be as clear as possible, and stylizing it is better done as you did in the second panel, to reflect Rarity's emphasis on "precious." In particular, I like Sweetie Belle's expressions and posing in the third and fourth panels.

The content is interesting. Obviously ridiculous, but there's absolutely nothing wrong with that. Some of the most entertaining pony comics are the ones that introduce to Equestria things that would never appear there in canon. The mix of our world and theirs is a great source of comedy, and I feel like you're leveraging it well--there's nothing at all awkward in how the Cutie Mark Crusaders are dissecting this information on atomic weapons and substituting things from their own world. Everything fits, and nothing is shoehorned.

I'm looking forward to the rest of this. As a Rarity fan, some of season 2 has been pretty underwhelming for me, but the Cutie Mark Crusaders are always reliable for a laugh, and I'm eager to see how they fail to get their cutie marks in THIS misadventure.
