I just caught a glimpse at your most recent set of Romulan ships. It's a good start, but here are some ideas that may help you fill out the set:

For the escort, you might want to make a Version of the Romulan Scout ship - that's the ship you currently have marked as Cruiser in the mod. That would be quite appropriate for the size and an expected addition.

For the frigate, I'd think a ship like the TOS or Enterprise Romulan BoP in a green would make a nice addition. The current Klingon with Romulan Green BoP looks decent, but try replacing the wings with those like the ones on the top right image. I think that would be cool.

You could then make a similar ship that resembles the current Frigate image for the destroyer size.

The Klingon Battlecruiser-like ship might look a bit more Romulan if you add a Warbird "Beak" to it.

I like the "bottomless" Warbirds designs, they should make good editions. Particularily the Top right one with the addition green hull designs.

I think the green hull colour you are using might be a shade or two lighter than typical Romulan ships. Try one with a darker green to see what it may look like.

Lastly, if you are using Photoshop for touchups - try using the magic wand (adjusting the "range") to select only the glare spot - see if you can fill that with a matching green!

Keep up the good work!
