Man, you tried, but I really feel like this is the kind of imitation of the Eldar Aesthetic which is the outcome of someone slapping together used bottles and stuff, like a kitchensink scratchbuilt of the Terrain.
Sorry, I think you missed the Feel and Designprinciples by a good long shot.
To elaborate; I think the Landingpad is quite nice;
but the rest; stuff doesn't organically flow, rather the tower and Bastion very much have the feel of a cut up bottle with Eldar Bits just tacked on. I also don't know what you're shooting for;
Eldar Vehicles and the Webwaygate have a Segmented Surface usually, intersperced with some more technical looking dood-adds and Gems, or look at the Voiddragon Phoenix from Forgeworld, which has almost something like a Runic Circuitry ontop of the wings. Where's the Antigrav-Fins on the underside of the Platforms?
But then there's another aesthetic, which I'd call "boney, holey, organically", which was visible in many old Craftworld terrain scratchbuilds, say:

and there's sleek interior design, bridging the gap between the vehicular design and the hollowed out bone design often associated with Wraithbone, say:

an then there's this, here on Dakka, which is
imho an almost perfect interpretation:

I'm sorry, but I think you're very far off the Mark at this point :-(
I hope I'm not crushing you;
but I think you need to take a good deep long look again at the craftworld eldar design, at buildings and vehicles we have, at the artworks and also at the designs for the howdah on the idoneth deepkin flying turtle for example :-)
