Very well done for early efforts! I like the bridge the best. The light is a tad harsh, but I think with some work in Lightroom or other editing software you could bring up the shadows. I'd like to see the top of the roof rather than having it cut off, and also more of the river in the shot. Of course, I don't know what your shooting situation was, so maybe you couldn't shoot any wider.
Anyway, you have a good eye. Keep shooting, that's how you get better. You are off to a very good start!
