Nidding's thread for learning architectual photography

Hello y'all.
I'm not sure if it's okay to post a thread like this, as I haven't been able to find any like it, but I figure that as the forum is under 'Learning photography', it could be relevant to have threads that follow the progress.
My idea is to post some photos through my development in learning to (hopefully) take great architecture photos.

I find the play with lines and angles, light and shadow very fascinating, but am just starting out in my way to understand how to capture buildings into images. Therefore I hope that any of you will help me o the way, and throw a little pointer or two in my way, if you have idea for improvements. All comments are welcome

I'll start with a few of my photos so far, to get the thread started.

Went out and took a few with my 18-55 kit lens. Not terribly sharp...
I feel like I get the most interesting photos when I take a frog perspective. Though I think this does have its merit in some case, I think I need to get out of this habbit, and try to use some more creative angles.
