This one leaves me at loss for words. I've been giving critiques to many art works and very few have left me speech less.
First of all, the colors of the photo look amazing. the light blue against the brown is so good. And I like that you chose the tower. The angle of your camera was really good because this way it doesn't seem unrealistic, you know. The clouds are looking beautiful as well. It's just a beauty... don't know what else to say.
I love a photo with a good detail because it makes it more believable to me. Every curve and line is beauty and this tower shows off a lot of it. I can imagine it on a calender.
P.S that white in the lower left corner is a little 'too' bright for my eye.... but the picture is fabulous. Good work
