The shot is trite and boring, sorry but I do not mince my words with snapshot level images.
Firstly it lacks a central focus or theme. As others have rightly pointed out this shot would work considerably better if taken from a higher vantage point, also increase the aperture at least 4-5 stops to bring the entire rocker cover area in to sharp focus.
Shoot it in colour, again for the reasons stated above.
Now for the niggling bits.
* The Carbon Fibre shroud is dirty. With engine shots like this the unit should be detailed (cleaned) to look it's best.
* Use a diffused bounce flash to illuminate the entire region with sufficeint light to produce a quality image, if necessary line the top of the engine compartment with white cardboard to produce a more even and colour temperature flash burst.
* Look for more interesting angles, this can be very difficult for newbies and those unfamiliar with the correct proceedures. But you will be rewarded if you attempt to think about your composition.
Good luck.
