When I see such strong chromatic aberration, I wonder: what is the point of this image? If it's supposed to be just a photo-like shot of an engine (not sure what this device is), then this chromatic aberration is too strong, because you rarely find it in modern cameras. If it's supposed to be a product viz for CAT, the it's too strong because it doesn't match the modern technology and looks just strange. If it's purpose is to show your post processing skills, then it's also too strong. No offence intended, I am not questioning your skills (I would probably never do such nice model and texturing), just rating the image.
