Very nice
I use to do stuff like this back in the day and what you have here is a brilliant piece of work love all the little details of the brick and rock and the ship and then the clouds and that brings me to the lighting within the clouds I think you could have a beam of light shining from the clouds to shine down on the castle or water even. Theres alot of nice little artistic and amusing things about this piece, I did however think you could have put more into it, so below and throughout the review are a few tips and advice that could help improve on this, but overall I found it to be pretty good.
