Of course all my comments are opinion. Welcome to the forums.
I like that your very first post is images. Most people aren't that brave.
I like some of these. The exceptions are #6 the contrail and #7 out the airplane window. I do have issues with some others and one observation common to all.
I find the steet musician acceptable but the weakest of the keepers. I wish it had more space on the left and the tertiary background element (the columns) cropped out making the image more horizontal. While I was cropping I'd also lose the foot just coming into the frame camera right.
#1 would get a huge boost minus the motorcycle.
#'s 2, 3 & 4 are IMO very good.
#8 is also very good except the shadow in the lower right corner was a huge oversight. Clone it out if you can, or care.
Your good images have a nice flow.....which you destroy with the hard black Photo by LUNA in odd places. It's like finger nails dragged across a blackboard in a quiet school room during a test while everyone has their heads down.
