nicely observed. i also like the angle and composition. not sure what, if anything could be done to improve the shot, let alone the challenge placement (unless there was some super wild skies--but then again, that would probably detract from the beauty of the building).
cool shot and it looks awfully familiar! very nice contrast between the blue of the sky and the white of the tzerkov'. are you from minsk or were you just visiting?
Slight wide-angle effect is a touch disorienting for me - has that falling over backwards feeling, a bit off-putting in this challenge. Technically accomplished otherwise, compositionally just a touch heavy in the centre without enough weight of interest to off-set that.
very nice building, but the lean of the verticals really spoils what could be a fantastic architecture shot. Difficult to control with a wide angle, but shooting from as high a stance as possible tends to reduce this effec a little.
Slight wide-angle curvature seen on the left. I believe you're allowed to adjust this in Advanced Editing, just use the Perspective Transform in PhotoShop. I do love the shapes, the stark whites in contrast to the other elements, the blue sky, etc. Good luck in the challenge.
