Thanks, I've only got one paint job that I feel is "ruined" and that's only because I had a better idea on how to achieve what I wanted after finishing it.
That said; I've managed to clean up my lines since this but I still haven't figured out how people manage to make their ships look... Right? Like every time I paint something I can tell its a painted miniature, whereas other jobs on here look like they could be production models from a movie.
My one recommendation for your A's and B's is do the yellow first, the black will be much easier to clean up with.
