One thing you might look into is using the Zoom function, rather than moving the camera closer to the aircraft, that will help minimize the FOV issues that occur if you move the camera too close.

There's not much of artistic value you can do with MS Paint. I use an OLD version of Corel Photo-Paint (got it way back in 1998, lol) and it has a number of filters and tools that can achieve those effects. I don't use them often, tho.
