Just for S&G, here's a very quick and rough version of what I'd do to the thigh cutaway. It is a thin line, so it may be hard to see...
To me, right now it doesn't follow the natural line started by the curve (which I like) in the bottom end of the body. Maybe the angle is playing tricks on me (it could also be the pickguard shape, not too sure I fully dig that) , and by all means, it's your design and your axe. I like the guitar, and hope it turns out awesome!
