Please critique my photography?

I like the Paris set - some interesting viewpoint & the B&W street set is pleasing.

Your portrait series (david steiner) is not quite so good. The focus is soft in many, The contrast is poor & the light is fairly flat (which gives your images a flat, 2D look). I could say the same about the other series (hadrian glaser).

In the 'Mountains' set the foreground could do with a little boost in the snow scene. The other two are rather lacking in any 'wow' subject matter.

Overall though I think it represents a good start. You have an eye for an image, I think you just need to place your exposures better & look at the lighting you are working with.
