Large areas of fibreglass without any features don't look "right", Beneteau flybridges like the 9m have a large piece over the front window. I looked at one of these as I was thinking of getting one ( or the 10.80 ) and I would have put portholes in to break up the white expanse.
I think your graphic is not in keeping with the resrt of your boat which looks business like and interesting.
How about a couple of lifebuoys ( old red/white types ) or something else with function? Perhaps these could be removable when underway?
We all have different tastes but for what it's worth I think that any kind of graphic/picture on a boat is very unlikely to look good.
I don't actually think there is anything wrong with the look of the Corvette......quite the contrary in fact so I would leave well alone. If you really want to break up the expanse of GRP then maybe a life ring (old red/white type as already suggested) or even another set of trumpet horns. Whatever I would suggest keeping it subtle
