Looks a little wonky maybe but I'm hoping it's an optical illusion because some parts are missing.
Required parts: pistol grip, red dot sight, magazine "skin", hand guard, charging handle.
Maybe some carving and sanding in select areas will be needed.
I think with the brown stuff there's a much better machined surface fidelity. It will undoubtedly take a lot more practice to improve but the results look promising so far.
