Thats not too bad really though. I know people who spend upwards of 100 hours on models, although they are usually larger monsters!
Im generally not patient enough to do a good job. My skaven army currently looks like this.
Painted: Queek, 2 assassins, 6 gutter runners, 2 poison wind globadiers, 1 warpfire thrower, an old skrye warlock, doomwheel
Half painted: BSB, 4 chieftains/warlords, warp lightning cannon, abomination, grey seer, screaming bell
Not painted: 200 clanrats/slaves, 70 plague monks, 10 plague censors, plague furnace, 2 plague priests, 75 giant rats, 8 rat ogres, 12 pack masters, 35 stormvermin, 5 jezzails, 2 ratling guns, 1 warpfire thrower, 1 warlord, 5 warlock engineers, 20 night runners, 1 rat ogre bonebreaker conversion, 3 poison wind globadiers and 4 rat swarms.
Salvage pile: Models that were painted badly: Vermin lord, needs stripping.
Something tells me this army will never get completed!
