I really like it. The only thing I'm seeing is that on the left, the way the carriage and one of the robot arms exit the frame, makes it so it's disrupting the nice circular path you've created with between the robot and baby. It makes it so my eye kind of wants to leave to the left instead of flowing through the scene. I think if you just made sure to de-emphasize that back arm and tweak the far left of the baby carriage it would flow with that pattern you've already created Another thing I thought of would be to crop the right a tad and extend the left a bit.
Anyway, I think it's really strong! It is busy, but that can all work to make a strong image with how you do your values and colors. Too bad they closed submissions before you could enter! Bummer!
