Maybe it's my monitor, but the picture of the building needs a like work. First, a crop and straightening is where I would start. That would get rid of the red car in the left corner and maybe prevent the building from falling over (LOL...sorry for the bad humor). Also the shadows, at least for my taste, probably could be a little darker. Adjusting your mid tones will also help the sky. I see a few clouds but they appear washed out. If I may ask, what was your exposure set for? Some of the other things I would try to get rid of (if your the software to help out) would be to eliminate the wire on the right side, and satellite dish on top of the building, not sure what that is on the left side on the roof of the second building and probably the flag pole on the roof of the main building. Hope all this helped. And I apologize for the bad humor.

Once you get them straightened using Lightroom, Photoshop, or something similar (though more basic) program, I feel both images are over exposed. The top one of the lake is easily fixed with a little darkening or lessening of the exposure in post processing. I see 1/2 to 1 Stops lower needed. The second image, the building one. I more over exposed. The brightest or highlight area of the building and truck are burnt out (the pixels over saturated or exposed until there is no detail). It might be fixable in the same way, darken it in PP. But I suspect it might require a re-shoot to get a good print or monitor image. Try setting the Exposure Compensation (EC) down by 2/3 to 1 Stop when you shoot in sun light. Might need more (less exposure) even than that.

Your composition is pretty darn good, especially the lake image. For the building / street scene, I'd crop out the fragment of a red vehicle that is in the bottom left corner. Though that would put the edge of the building on the new print edge. Personally, having the skills, I might clone it out instead, replacing the car with pavement. But correct the level issue first, then the exposure issue second. Lastly retouching blemishes and cropping.
