I love your Mad Moxxi Cos.! It's not "over-breasted". Sure she has large one's ingame but yours have just the right amout (not being creepy here but I think this need to be said). It gives you room to focus on the other lovely details on your cosplay.
Tlr: A well made Cosplay is better than just Big Breast + Cleavage and no efforts!
I hope this doesn't sound as bad as intentioned ^^"
You are so beautiful and talented at the same time. First this neatly done costume of such an inspiring but still hardly used character and second these big shining eyes. in short, every man in the world would be happy with you.
