I have been drawn to architecture type photography in the last few months. In particular I have been focusing (a pun...hehehe) on larger tall buildings in Cities. It is amazing what one can see when one looks up in the city.
You first photo has my attention for the above reason. I like the angle, lines, different building styles, shapes, textures, colors, and the shadow you captured, and lighting differences all in one photo. Even though the angle is a random angle not following any of the building lines, it works very well. +++
P.S.
If you have not tried this already; stand fairly close to the buildings, such as you have in your photo, turn you camera so the top lines of a building are parallel with the top frame of the camera. I like those angles the most myself.
