Thank you guys.
how long do you take to paint an only unit at this level?
I would calculate 10h for a unit of halberdiers, 7h for xbows. That includes priming, varnishing and basing. I'm painting very slowly and could save an hour or two or even three if I sped up. But correcting small mistakes I only know of and that you wouldn't see from more than a foot also consumes time.

But hey, these guys fight for me so they deserve a good treatment! For my next units I will try to check the time.
@banner:
The banner with the sword I already had in stock. It was the banner I originally painted for my greatswords. But somehow it didn't look mean enough for an elite unit. So I painted another one for them with two bigger swords crossed and had this one left for the halberdiers. That's why there are only 5 guys in the front row.
But this kind of banner painting takes too much time for me and now I'm going to stick with more simple patterns as they also give a great effect from far away like on the other unit.
