Welcome to the forum Shay!
You've got some nice images there, compositions are reasonably good with some nice colours and you've controlled the exposure well keeping nice detail in the clouds. I do notice you've shot 2 of these at f3.5 which isn't the best for landscapes as the depth of field is too thin meaning these shots are not as sharp as they could be if you'd shot at f8-f16 which are the apertures more used for landscapes shots as youve a deeper depth of field. There's a little posterisation in the sky, though that may be due to compression and not in the originals. Theres also quite a bit of CA that could do with being removed. I also try and straighten the buildings a bit (I find the wide angle filter in photoshop really good for this).
