Thanks guys.
I think I'm least happy with the greenery myself. I'll have to try something different next time.
I agree with the comment on the rocks, I was pleased the way they turned out. Then of course, they are pretty much hand painted over the line work. I probably should have posted just the drawing without any color in order to make a real WIP out of it but it wasn't supposed to be a long drawn out work anyway. I also was pretty happy with how the reef islands turned out.
As for the Sea, I'd call that my semi watercolor attempt. Combined with the line work It came out sort of how I envisioned. Sometimes you get some happy coincidences too which are always fun. I faded it outwards using that eyeball blur thing PS has which leaves the focus on the areas you want but blurs the areas outside of it. Not a bad tool i think.
