Thank you for the responses.

I made a few small changes. some are noticeable just by looking at the picture, and some are not unless you take a look at the original. so here it is

Several of the small changes included making the sky a little darker, more saturated, and then turning up the contrast on the 737.
For the lighting effects I made the sides of the clouds that faced the direction of the sun a brighter white, and then most noticeable, the darker spots on the corners of the picture.
As far as the painting look goes, I think the main reason that it had that effect, was due to the slightly darker, truer, colors that the picture had in it, and the look of stillness.
