Your photos aren't "bad", that's for sure

Nothing leaped out at me that shouted "bad" but nothing shouted "amazing" either, and that's not a bad thing at all... My photos were terrible for at
least six months after I got my camera and I still take horrible ones

I left a comment on your Wharf photo, as I think that is your strongest image out of all of them. The cricket pitch photos would be my next favourite ones, as I think I'm liking the negative spaces in those photos. My least-favourites of the bunch are probably the ones taken at the beach. They're all underexposed by about a stop or so, and to me they aren't overly interesting to look at... There are lines, yes, but they don't lead anywhere and there's a lot going on in each of the photos so they don't capture the viewer's eye.
For the "Waveless" shot, think about maybe making the blues a bit brighter, in doing so you keep the silhouettes of the surfers but bring the contrast up so that it has more impact

Hope that helps!
Edit - As an afterthought (and not to get into a debate) I
highly suggest shooting RAW, even as a beginner because it allows you a LOT of latitude in correcting exposure mistakes as you're learning your camera, and later more flexibility in getting a desired "look" rather than dealing with some Japanese engineer's settings in the camera regarding contrast, saturation, or sharpening

I've gone back to images that are ~4 years old and re-edited the RAW files I shot and the difference is like night and day, almost hilariously better now...
