The first one doesn't do much for me, but I'll give you its a different perspective to any of my shots of the lighthouse.
The second is lovely I'm sure you happy with the result.
The third and fourth! I hate you, I was there for both of these and tried to take similar with my D70 and 80-200 , the equipment and skill of the operator shine with these shots as they blow mine away in every way.
The icecream is a classic, you can't even tell it was low light!
And here's looking at you, got to credit you minimum trace of the harsh lighting that this shot was displaying on the D70. Masterful stuff!
To prove the point here's my version.
