What I enjoy about the photos you have posted is the composition of the images. That's what makes a photograph work. the second and fourth images, black and white, are stellar. Great tones and lines. You can learn to use the camera, learn lighting and just about anything else. Composition is something you have, that artistic eye, and not something you can learn. I have seen people take the most beautiful photographs but the composition of the photo isn't there. Many photographs make you wonder why the person pointed the camera at what the shot.
Keep shooting. I like them.
