Get rid of that circle on the end. Make the iron sight nonexistent, make the Magazine smaller.

Thin it a bit. Destroy those triangles

At the monent the barrel is done very sloppily. You need to use straighter lines and try using rectangles and triangles

MUUUUUUCCH better!
Though the front still bothers me.
I want you to look up something called the ‘Lancer’ from a game called ‘Ratchet and Clank 2’, look for gun which is orange and has a long barrel, try basing this gun’s barrel off of that one

(lol at the sexuality bit)
well maybe try to just remove that big circle in the centre as it’s a bit too plain, maybe replace with a vent looking thing or something

it still looks very unwieldly though, the sheer size of it would dwarf the wielder. maybe consider trying to remove most of the central mass, adding in those iconic Rouxian patterns and flattening off the ‘shooty-bit’
