Have a look at the "Hot Bird of the Week" pictures on the Two Bobs website.
In fact, they look about as realistic as the SA-43 Hammerhead seen in the science-fiction series "Space: Above and Beyond".
I always find that smaller scale models look far more realistic when they have lots of lumps and bumps and dangly bits. Lots of stencils, properly applied, also enhance the realism. I wonder how realistic small scale model F-22s will look, given that the real things look like second rate TV props!
