Unique designs like these always reveal hidden talents which you clearly have. Well done! If you haven't already checked his stuff, take a look at Parrington Levens GAIA builds. I think you'll like what he's got there.
Now theres something worth commenting on! The various angles are nice but the curve technique for the wings are the true center-point of the build. I think the inverted-slopes on the very edge of the wings could use some work, though. I think it could use some more color-unless you want to stick with an all-grey creation. If you do want to start building in only grey, I have a theme that would love to have you! But theres another, just as great theme, that uses grey and red seeing as you seem to have plenty of the 2x2 red tiles. Overall, 4/5!
Nice pattern you made there with the wings on the sides. A red stripe along the ship would have added a pimped touch and I feel the thrusters should be more integrated. And a landing gear maybe? But good work on angles, concept and size! Nice one, keep 'em coming!
Oh, nice! Love the design with the unique angles. Great parts usage throughout, as well. I think just a tiny bit of that red elsewhere on the ship would be a sweet little touch, or maybe even just a couple of stickers with some red in them. But whatever, this is a great little MOC - nicely done!
