I have spent several years working in digital painting and photo editing, and I must say, this kind of this is right up my alley in skill set. Personally, I am best at editing nature scenes, usually macro photographs of flowers and other plant life, but I also have skill in editing mechanically inclined scenes, such as classic car headlights and silhouettes.
Should you hire me, I would be extremely communicative, providing continual updates of the work in progress so that you would be able to provide your own input and ideas so that the end result is as near to exactly what you wish it as physically possible. If you have any questions of concerns, I would be happy to address them at the start of the creative process.
