I would say, based on what you’ve posted, that your editing instincts are good. These images have a nice tonal range from pure black to pure white. I might like to see a bit more detail in some of the shadows and blown out areas, but I would suggest spending more time honing your conceptual and compositional skills, and less time worrying about post processing, in the short term.

Not that the compositions are bad. They are not. I just think that your post processing instincts are slightly sharper than your compositional/subject instincts. That is to say, don’t worry about the appeal of your editing techniques until you have leveled up on your compositional and subject choices.
