I was looking at them again, wondering about why I chose #3 as Keith liked #1 and #2. I love the lighting and treatment you gave all three... Personally, I like #3 because it looks like random shot where a motor was being assembled and you were shooting that... and that leads into a backstory and wondering what else/more is going on. I love #1 and #2 from an abstract perspective, but they don't have the story.
So there you have it, my art critique. lol I can't come anywhere close to creating that art, Eric, so take it FWIW.
