UPDATE...
Well except for a few very minor tweaks this ship is done.
Here's a look at two more ships. These designs come from Jackill's Starfleet Reference Manual ships of the fleet Vol. 1. I desided that I make them as TOS ships. I used the active shade renderer in Max for these shots that's why that don't look that good.
Swiften Class Fast Destroyer
Cheetah Class Fast Cruiser
I thought I'd throw in these very rough blocked in ideas for three post Nemesis ships.
I don't garrantee that I'll finish these ships. There just ideas for now.
