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 ^^"
