As a 501st member who has trooped with mandos (and I have an unapproved Boba), I can say without a doubt that you are going to be called "Boba Fett" a lot with that outfit. I started my mando in march. I would never do a mando in green with a grey jumpsuit. A major reason I procrastinated for a year before starting after telling everyone I troop with that my next project would be a mando, is how much trouble I had picking a color scheme and armor design that wouldn't be confused for Boba or Jango.
I have given up on correcting people who call Ein Karell "Boba Fett" when we troop. He's forest green and orange with a dark grey jumpsuit and horns on the helmet. Last time we trooped, there was a movie licensed standee of pre-pro Boba Fett right behind him and a woman walked up with a child and said "do you know who that is? right, that's boba fett."
Again, yours looks good technically, but it also looks from an outsider's point of view, like you tried to make a Boba Fett from memory and painted some parts wrong. You definitely put it all together right and did a good job. I just want to warn you about the sentence you're going to be saying at every troop outside of major conventions: "no, I'm actually a custom mandalorian, not boba fett."
