I'm about 95% done with my custom color #EntryGrade RX-93 Nu #Gundam after roughly 4 months of working on it off and on. I used an airbrush to paint and topcoat it. I also used homemade oil panel line washes; the gray one turned out terribly, as you'll probably notice if you zoom in.
Shame on Bandai for not including a beam effect, though. I had to mutilate one of the extras I had to make it fit.
