I definitely used to do the same kind of stuff, though I always went with my mom and bought like... a foot of fabric to cut up off a roll. Quite a few of my MoC's incorporated that, mostly to help hide my hideous work
I like the updates! The arms look a tad long still but at the same time I don't know if it necessarily bothers me looking at it stylistically. Mostly, I've got to say that I'm impressed with the fact that there are really no noticeable gaps in the build.
Then again, I'm an old timer. This new CCBS stuff is alien to me, so who knows, maybe it's not impressive anymore... either way, I like it, and there's a ton of potential here to improve as time goes on!
