Beautiful image manipulation! The blurred castle in the back doesn't do it for me, unfortunately. Everything else is so natural and organic and it doesn't stand out in the brightest way. However, the rest of it is gorgeous, some of the pieces almost look like coral! Great eye for detail.
This is really beautiful! I especially like the foreground with all the green and the water before the waterfall. The only thing that makes this piece less than perfect would be the blurred castle/city. Overall, this is wonderful.
That is absolutely magnificent, it has a very magical and surreal feeling to it. But the city in the background does look a little to blurred compared to the surrounding stuff that's roughly as far away, I would suggest either sharpening it up a bit, or blurring the area to the right of it a little more, but all in all this is really, truly amazing.
