Mooshoo, here are a few comments in general.
1. Lighting
These shots look like they were taken during a very sunny day. In general, very sunny days can be difficult, especially if you do not understand how the settings of your camera work.
Each shot is either overexposed or has portions of it that are overexposed.
If your limited in time to shoot, and have to shoot during the "highnoon" time, either shoot in the shade or learn more about your settings
2. Focus
It may be the screen, but the shots are not well focused.
This and the overexposure makes it difficult to see your shots.
3. Composition
I can see what you are trying to do with your composition, and I like it. your subjects are good.
So work on your technical/camera skills and your improvements will come quickly.
