Slick Cam at Thomas Point

Thomas Point Lighthouse is a historic screw-pile lighthouse in the Chesapeake Bay near Annapolis, MD. The term "slick cam" is used by the local waterman meaning "slick calm" i.e. no waves. I wanted the painting to look serene, and to "pop" with bright color. Artistic license was used to achieve this.
The original file of this was intended to be printed at 30"x40" and still remain sharp. I think I achieved my goal.
This took around 60 hours or so, all in Painter X with an Intuos 3. I referenced about 30 photos of the lighthouse from all angles and heights but can't say either one was a model for mine. I used the raw dimensions of the structure scaled for the layout. The rocks are totally made up, the boat is from a photo of mine. The birds are all from stock (links below).
I'm having fun messing around with different backgrounds on this, so there may be another upload.
Critiques are requested. I have been studying the digital art of Stephen Harlan (harlaneditions.com) lately, and am aiming for the same effect he gets with his work.
