I'd probably knock the blur down a bit and get rid of the lens flare as there's no real need for it.

when you are trying to match a background plate the goal is to match the elements that are there in the plate. Theres no light source visible in the image so there wouldnt be any lens flare. plus there is little or no depth of field blur on such a wide view so there would be no need to blur the object. maybe choose a camera view that isnt so far away from the subject with obvious shadows, maybe a clear focal point so there is depth of field (as in there would need to be a foreground middle and background in the composition) and obvious lighting so its easier to see the elements you are trying to match.
