Much will depend on the judges' interpretations, as well as the level of competition. Your renderings of the sun on sea in the first two come across as "crunchy" to me, and could be interpreted by some judges as technical flaws rather than artistic choices. Also, without the artistic rendering, is there sufficient interest in the images? While artistic rendering can absolutely enhance an image, rendering alone typically doesn't cut it (especially with a seasoned judge).
#3 is appealing to me. I like the graphic nature and composition. I don't mind the "graphic" saturation, but others may disagree. #4 is a pleasant and competent photo, but may not have enough to elevate it above other such pictures. I might experiment with B&W for that one.
I'm glad you don't "bruise easily" because competitions are really a crap-shoot. I've seen really good pictures get "picked apart" for the most minor technical issues, while the obvious (to me) merits of the image get ignored. Most judges try very hard to remain objective, but often there is a lot of subjectivity in their opinion.
