Have you tried moving to the left a bit so you could get a bit more profile on the buildings next to the lighthouse? Is it possible at all? Also, not sure what look you're trying to achieve with the coloring... right now, I'd say the somewhat overly yellow cast can be a bit distracting. What kinds of different lighting scenarios (early morning, sunset) have you been able to try? Difficult I know, but trying to get this cloudy-ish with a ND filter could be great too.
In any case, a location that definitely has great potential, you'll definitely be able to get something great out of it... wish there were places like these within bus range of the Ottawa downtown
