"Transport someone to a place from another" is a good start, but you can give that idea much more detail. Is it a one-person transport, or can it take passengers? Is it a military, luxury, or common civilian vehicle? If this was a car, what would it be? Formula 1? A muddy Jeep? A Lamborghini? A big, fancy, black Lincoln? A cheap sedan? A family minivan?
- How does it land?
- How does it thrust? Can it take of vertically, or does it need a runway?
- How does it steer?
- - If it's an aircraft I would expect flaps and maybe a tail rotor
- - If it's a spacecraft I would expect thrusters
- - If it's multipurpose, have both
- How do the crew (and passengers?) get in and out?
I'm not sure about that round thing in the middle. With its high contrast and circular shape it draws the eye much more than any other part of the design. I don't understand its function. The way you've drawn it makes it look like a cone-shaped hole in the ship. If you take it out the design is much more sleek and unified.
It's hard to tell the form of the front part of the ship's body. I guess it has a diamond-shaped cross-section (which is hard form to show), but right now it seems to be almost flat. If you make the cockpit transparent that would help show the form, but you may want to make the design wider.
The rear set of 'wings' are odd too. They seem much too bulky and the wrong angle to be wings, but the scale of the ship seems too small for them to be extra body sections.
That reminds me, you should have some way of showing the scale of this ship—seats in the cockpit, a row of airplane-size windows, etc.
Maybe looking at cutaway diagrams and photos of helicopters and the space shuttle can help you with adding the details:
Apparently helicopters have a ton of small antennas. Also air intakes, exhaust, running lights, etc.
