I thought I'd quickly make an HGUC Guncannon to take a break, but it ended up being so fun that I started doing all sorts of things.
First I quickly glued together the seams of the parts that could be removed, and replaced the antenna with brass wire.
I added some detail by sketching out some of the lines.
It's supposed to be a space combat unit, but it seems like it doesn't have enough thrusters for attitude control, so I started by changing the angle of the backpack.
I've added thrusters little by little to the backpack. From here I'm thinking of adding a small propellant tank in the middle.
