Well, here's my collection, in chronological order from when I started four years ago up to my latest one. Most of these have been sold, so they technically aren't part of my collection anymore, but since I built them I figure they still count.
I have 11 more over 90% complete...but as I get better, I build slower and don't call it done as soon as I used to

StuG III, Oberwachtmeister Hugo Primozic, Eastern Front 1944

Hopefully you can see at least some improvement, I do think I've gotten better since that decidedly mediocre Opel Blitz
