Dylan, I'll have a go.
You have nice lighting in both images. Certainly an important part of any image.
In the first image, there's no real subject. Possibly the building. When you look at an image, if you find your eye wandering all over looking for a place to land, you have a problem. Your eye should naturally find its way to the main subject. Even better if it is led there with a "leading line" like a fence, stream, etc (obviously depends on subject matter). In this image there are just a bunch of disparate elements.
In the second image, well, it's just a sunset. In order to elevate a sunset image to something special, you need more to work with than what nature is giving you, and your choice of composition here. If there was an unbelievable sky, you'd have something. With just flat water in the foreground, that isn't helping you either. Some strong element in the foreground would add a lot. A pier maybe.
Keep shooting, mate. You have an eye for lighting, and some great gear. Find images you like on the web, and then figure out what makes that image appeal to you, and work that into your own shooting.
Hope this helps!
