I think it is safe to assume you are still quite new to photography as well, so I'm not going to critique each individual photo but rather give you an overall "what to look for."
The first thing I notice about your photos is that you are lacking a clear or interesting subject. Your subject can be a group of trees, but what makes them special? Try to bring out that special quality about them, that can't just be captured by the human eye when you just walk by. Speaking of the human eye, if you can see it standing - it will not be an interesting photo. You will need to move, and a lot! Remember, if you take a photo from standing height - anyone could just walk by and see it for themselves. What makes a good photograph special is getting a new angle on a subject.
All of these look like decent snapshots. To quote myself from another thread:
" Intent is what changes a picture from a snapshot to a made image. Control over lighting, positioning of subject, experimentation, knowledge of composition, and a bit of luck make a good image. Knowingly setting up a scene for success is what makes a real photograph

"
You have what appears to be a good understanding of the technical side of photography, now it is time to start experimenting! These are all properly exposed, and from what I noticed in focus. Now you should start moving on and coming up with new creative ideas

Try some fun techniques like the ever popular light painting, panning with fast moving objects, ink drops in water, smoke, whatever! Just keep at it
