Another model I've started work on is a Romulan/Klingon Hybrid, the Lammergier class Heavy Cruiser (or maybe Light Dreadnought). There is still work to be done - warp core are still to be built etc, but I quite like how she's turning out, although I have reservations about the back of the secondary hull, but there's time to work on that.
Starforce2 & Azel - re the Rom Merlin, I've taken your comments onboard and have been trying a variation to improve the forward warp pylons - so far I'm not keen on the results, but I'll persevere.
James Formo - re the Merlin, I'll forward her to you and hopefully you'll be able to sort her out and make use of her.
