Here it is we built these for last halloween over a couple of weeks. Using mostly just parts from around the house.
Not too bad for a junk pack. I’m sure people at party’s and stuff will dig it.
Yeah pretty cool. I’d say put a few more doodads on there. Maybe a knob here or there and call it a day. 
The main look of everything seems to be there! I’d say add the N Filter red stripe and white circles if possible. Maybe do some stuff with the proton gun. Very nice! Just some thoughts 
That’s just what I’d do personally. It’s amazing how many little details are on the packs.

A better first attempt than my own, to be certain. At least I can tell yours is actually a proton pack! 
<–not a fan of junk packs either.. kudos for the build cause we all gotta start somewhere, but junk packs are not my thing
