When I first saw this piece, I naturally took a liking to the biggest, most powerful looking mobile suit, and that one was the one on the top row, third from the left. I don't know what it is with me and oversized weaponry like that, but who cares?
I like how you included the chibi versions behind each one, and the unchibified versions really take the cake here (as well as a good amount of space as I noticed)!
Re-count the number of machines.
Now look at your comment.
You now have my permission to be embarrassed.
