Hmmm... hard to say about the figure quality, I've never done a 1/72 figure...
I will say that the airbrush work on the Panther roof looks exceptional though
But seriously, doesn't get much better than that- red piping from a single bristle to achieve some amazing scale thickness- only thing I might say negatively is next time, I'd tone the red down with some gray to give it some scale darkness, it looks too bright, and stands out too much for my taste... of course thats probably just so you can show it off...
