I took this picture in Amsterdam, Netherlands
I loved all of the different building shapes, the canal, and the bikes.
I like your shots and enjoyed seeing Amsterdam, thanks. I like #2 best.
I agree with others there are some details you can clean up, like wires and extraneous clutter. I agree on a slightly more cropped view on the statues, but I think your crop in pp was a little too much. I would have liked to see those side panels in the shot, but not the window on the far side or the gutter, etc.
I also think you can strive to straighten your landscapes and find better light when possible.
In some of these pics I think you could have added some drama and interest by, say, getting down on one knee and shooting through the fence or upward, downward, etc. I think you could have done some nice and unusual shots using the bikes and maybe the boats. Looks like you were on that track with the buildings in the last shot. I kind of like that smallest building on the left in the first shot. Maybe you could have done a vertical shot with the bikes out in front and incorporating the signs, all of which have a lot of color and texture, etc.
Besides the light, these are examples of composition. So if you want to improve in that way, read up a bit on composition.
The light issue is about exposure, and you could improve on that by reading up on it as well. Are you familiar with how to use your camera's meter?
Changing lenses will improve your perspective. As long as you follow the guidelines for changing them you should be fine. Don't let that hold you back from experimenting with lenses!
HTH a little. Everyone's got a different idea of these things but there are some general principals that can really help improve our shots once we embrace them.
