Some decent ideas there and more importantly, since you are new to this, stuff to learn from. Purely from a constructive angle, I'll point out a couple of things.
- In the images where the horizon can be seen, generally, you want to keep it level.
- Try to strengthen your composition by learning about stuff like the rule of thirds, framing, balance....It will help you develop a photographic eye, even if later you do break those guidelines (because there are always exceptions).
