Great photos dude, your work deserves to be seen. Have a search around for photo contests. I've got some great feedback, if not a lot of steem, but it's early days for me too.
Also take note of the various photography related tags you see from high value posts. I keep a list and I think #photofeed has been pretty good. I pasted in my list below, but do check them out, I don't know enough to be sure which are the best .
