Hey your unfolds look really good, I have one or two tips to make em even better. Before you even start unfolding, right when you open the file, go settings -> other settings.
Near the bottom there should be a check box that says "Hide almost flat folding lines" check the box and set the threshold to about 155-160
This should get rid of every unnecessary fold line (the ones that just end up getting smoothed out later) and results in a much cleaner unfold and pep.
Also once you finish an unfold (or even half way through one) click 2D Menu -> Join Adjacent Edges, put the number that pops up to .60 for pep unfolds and 1.5 for foam unfolds
I hope this helps make these even better!
