I like how you have the guy walking by a tree on a couple of the backgrounds, looks cool, I think something “outer space” might fit better though.
The graphics of people working together (one with a conveyor belt/office scene…) feel generic to me. No disrespect intended. I realize you put time and thought into it and they do send the right message. I’ve seen similar graphics on other websites and they don’t appeal to me personally. I suppose it’s a matter of personal taste, I look at originality where most people sort for familiarity.
