First off, I think "Dominican Pirates" is a marvelous piece!

I noticed, as others mentioned here, that some of your Vue renders look too washed out or foggy. In some of those, it looks like you are adding a fog effect post render. If that's so, you're missing out on one of Vue's more outstanding features. Take some time to fiddle with the atmosphere settings. Vue can produce some great fog/mist without obscuring foreground details. No post work fog needed.
