Sure.

- Pump up the colours! You could for example have used this paint, or one similar:

[It's the same aircraft, actually the very same model]
- You could've gotten some sky in there, with some clouds, that's always good, that would've given the shot some contrast too.
- Also, give the aircraft some movement, example; the shot above.
- I really don't like those ground textures, if you like em', keep em', but in my opinion they don't look good, in screenshots at least.
