Well done for catching up
Leave Good take on the theme. I find the bottom of the passport a little too oof though. Do you work at a university? That leave record form looks very similar to the ones we used to use.
I prefer the off centre shot of the wood. The angle of the knot even points into the space so works on that front as well. As an abstract though my vote would go with the vacuum cleaner though. It's nice and vibrant and possibly fits the theme that little bit better
