I LOVE this design! It seems more clever than the design of the Dreadnought Class in ST-ID. It makes more use of cool shapes rather than bumps and greebles. It has a level of detail without going overboard on the shapes of the hull. I also like the addition of the lance; it gives a reason for the saucer ring to be there, like a power concentrator ring or something like that.
As some more constructive criticism, I might suggest making the saucer more polygonal, to match the style of the rest of the ship. As a tangential experiment, I may try getting rid of the saucer altogether, a flat, rectangular projection on either size of the lance, or something wildly different. In fact, I may just have to do that!
