Nice! I hope my first pep helmet comes out as nicely as yours did! I agree that the other parts you've posted look a little oversized for you, but the execution of the builds look as good to me as your helmet does.
And I don't think that 3 weeks from first post with helmet to next post with more completed parts (oversized or not) is excessive at all - I went a couple of YEARS between my first few posts and getting back to the group again just recently, and STILL don't have anything even pep'd yet! Though I hope to fix that tonight, actually (trial run with a Mk VI helm from the Hub, this time printed with the numbers attached...
).
