My Nids are done. I had to make a slight change to my vow since the tournament rules changed as I was painting them, but basically I just didn't base 2 genestealers and 1 tyrant guard out of the bunch. They are painted though.
I've painted and based: 10 Genestealers, 6 Warriors, 2 Raveners, 1 Tyrant Guard, 2 Biovores with 8 Acid mines, 1 Hive Tyrant, and 1 Carnifex.
Also painted but not based: 2 Genestealers, and 1 Tyrant Guards.
And already painted but had to base: 16 Genestealers, 16 Hormaguants, 8 Termagants, and 1 Carnifex.
Not bad for a month's work.
btw, I placed 13th out of 20 at the tournament, by winning 3 and losing 3 games. My best tournament ever!
