Hey, welcome to POTN. Good way to introduce yourself
These are good pictures!
The first and second are the strongest. The first because the strong diagonal both gives the image a strong composition and hides the distortion from the wide angle. The second has a great leading line. The third lacks the strong diagonal of the first and so the wide angle distortion is more obvious.
All of them are well exposed, with good colour and interesting subject matter. Hope you post some more stuff. I'd like to see what else you have!
