Above all, I really loved its design, I liked its reminiscence to the Interstellar´s Ranger, the textures and the level of detail it has so far and all, but to me there´s one thing that still bothers: the wings.
Why does it have such small wings for a planet like Mars with almost no atmospheric density at all? Judging it for its landing gear, it is designed to land horizontally but it would fall like a brick if you try to fly that ship with those wings. Or was it designed for landing/taking off vertically on/from Mars and then for reentry on Earth?
I think an Ascent Vehicle does not need any aerodynamic surfaces at all for a planet like Mars and because most probably it would be used to just reach low orbit and dock to an already orbiting ship or station. Aesthetics aside, I think that it would have been more appropriate for that goal a ship similar to "The Martian" MAV.
Overall I think its design, although being awesome, doesn´t make much sense.
