Wonderful work with all of these photographs.
Your ability to compose a clean composition seems to be something that comes naturally to you. Your messages are always clear and there is a common thread of story telling in each of your photographs so far.
My only concern now that I look back on your images, is that you haven’t used light to experiment with mood yet. I see a lot of moodiness and emotion in your work, but your lighting doesn’t complement this. You tend to work with front lighting which always strips the emotion out of a scene. Front lighting is the type of lighting used when filming comedies because it’s safe and exposes everything equally. The downside is that it’s flat and a little lifeless. It also doesn’t draw out texture because the light doesn’t mould around your subjects or objects. Front lighting washes your entire scene the same so shadows aren’t given an opportunity express themselves.
I see a LOT of potential for texture and mood in the following photographs (especially the photographs with the hands). However, in order to draw this out you’ll need to experiment with different intensities of side lighting. Side lighting will mould around the fingers, casts interesting shadows and bring out the texture in the skin. It will be a much more dramatic and moody image if you use side lighting to light it.
For example look at the following photograph:

you don’t have to like the hands or feet, but look at the texture in the shot. The shadows are created through side lighting. The textures are found due to side lighting. The mood is set by side lighting.
So play with this idea a bit. I think you’ll be happy with the results!
Good luck
