What's with that funky multi-coloured island in the middle? It seems to have red trees but there is no beach on it, the texture goes right up to the sea and just stops. Looks a little plonked on.

I can see why this took you a lot of time, there is visibly a lot of work gone into it.
I am curious though, with this being copyright of Tin Hill Press, does this mean it is a paid commission? Just wondering as your words suggest there are a lot of man hours involved and I can't imagine your hourly rate worked out very high.
