Very nice work!

All that mottling turned out really good.
I'll have to second Rowan about the fogging.
Using super with clear parts that form a sealed space where the fumes can't escape freely are at risk of fogging. I've heard it to that clear parts dipped in Future should be resistant to fogging, but I haven't tried that myself.
PVA and similar glues are indeed a safe choice with canopies. Microscale Kristal Klear, and Gator's Grip glue are worth checking out too.
If you're thinking about getting a new canopy, Falcon has a vacform canopy for the E-3 under their Squadron canopies line. It says its made for either the Hasegawa or Tamiya kit. Zvezda's
F-2 and
F-4 kits come with a whole extra canopy that goes unused, which to my knowledge is suitable for the E-3 (
sprue picture, on the right). There could be folks out there with the extras they didn't use. Of course, there's always the option of buying the whole kit...
