Im not seeeing him fitting into the EA assylum security, but thats just me.
Ok, lets start with the story:
Hamelin works for the asylum, he's one of the only guards who can bring the in mates in without even getting a scratch, due to his hipnotizing Pipe
Im quite sure that the guards are reserved for the outbreak of the most dangerous inmates (AKA: Red) so im placing this guy alongside the "compensator gatling gun" guy and LT. Borsley (special/named guards, therefore getting more panels/lifespan) that apeared in the prolouge.
That he can survive that long thanks to his jigglipuff pipe sounds like it fits the EA world, though im sure the other guards will need to use very good earphones.
The costume is nice, though I would recomend making it look more like one of the guards (hes a guard after all, right?).
Try making him a bit stronger or older and try making the start and end of the elbows and wrists a little more noticeable.
Try giving him less of a girly look, the other guards will probably tease him for his long hair.
