Yes you are going in the right direction. Some interesting and insightful stuff in there. I enjoyed looking at your pics.
To be honest, I am always slightly thrown by the "should I continue" question - that is up to you! If you are getting out of it what you want to and are enjoying it then of course it is, regardless of what other people say. It is a personal thing.
Of course I understand it is nice to have anothers opinion of your work and I think you have a good eye for a shot, clearly understand the techniques and your composition is generally really good.
