Well first of all, if you are going to be posting multiple pieces in a day, you need to create one page that you update. Having 4 threads on the first page by the same artist tends to clog things up. As for the manip. If your just going for changing colors on a photo then you did a good job. But if you want something artistic.... There's nothing to it. You don't have any focal point except for a large blur. Sometimes that works, if the blur is to represent something like the sun as it sets or rises, but because you changed the colors, we don't know if the sky is of the right color for that case. So as I said your only focus point is a large blur, which is rather boring. Sorry if it sounds harsh, its not supposed to be, just c/c.
