I could use some advice.
 

Every year, the Arboretum Photographers Society has a juried show and sale at the Arboretum starting in January.  The submission deadline is in October, so I need to figure out what would be good submissions.  That's where you come in.  I'm going to show a bunch of photos below and I'd really appreciate feedback on which ones you think are worth submitting.
 

The title of the show is "Seasons of Light", so interpret that however you wish when judging.

This first one I'm just going to submit since I already have a framed print sitting at home, so it is essentially a freebie for me.
 

These next images show how light is bent by heat during a controlled burn [For those of you who are not familiar with those, there used to be massive wildfires on prairies that would burn off all the growing plants, leaving prime soil and helping native plants propagate.  These are now done in very controlled circumstances to make sure they don't spread  to unwanted areas, like houses.]

My personal preference is for the first one showing the Fireman, but I'm curious what you people think of the others; especially the last two.
 

This next set are more abstract, showing light more as color:
