Home Stretch:
I'm about three quarters way through the second Buypainted video on all my Tyranids:

Where I just applied the satin varnish to the models, Jaro can talk your way through this much better than I can.

Now I need only finish the claws, teeth and mouths, apply the wash and seal the models.

This is but a small sampling of the models; missing from the photos are the Harridan, Tyrannofex, Gargoyle Brood, Ternagant brood, and Hergamont brood.

Following Jaro's Trygon instructions and transposing them to the rest of the menagerie I managed a reasonable facsimile of his work; not perfect but better than I hoped for.

Interesting that the Trygon head is about the same size as the much larger Hierophant's head.
