No replies yet and it's probably because you set the bar a little high. Maybe no one wants to claim (or admit) that they know what they're talking about. And generally, the people who
really know what they're talking about are too busy doing professional work to post in every thread over years and years. So I hope you're not discouraged by the lack of replies or the fact that the first reply is from someone who doesn't know what he's talking about. Take the following with a great deal of salt.
The first thing I notice is that you're dealing with very unusual, small and intricate shapes. Those three things are hard to pull off together. If you want something small and intricate, it should be a shape people are familiar with (e.g. a chess piece or a portrait). If you want something unusual and small (like a house made from donuts), it should not be intricate, it should be simplified.
Looking at the top view, I think it's hard for me to wrap my head around what the shape of the ship is. It looks like an abstract geometrical pattern. I can't tell if it's shaped like a cone, a slice of pizza or a butterfly, unless I have the side profile to compare with. And again, the shape is small, unusual and intricate. It doesn't look like a typical rocket or X-wing or Raptor-esque fighter. I can't tell if the wings are flat or vertical surfaces or concave.
Finally, I should say that using more bulky and less intricate shapes allows you to add more detail (e.g. rivets, decals, plating, etc) which
can be more visually interesting than a bunch of smooth shapes stuck together.
That being said, I really do applaud you for coming up with an unusual design. The side profiles are really nice. Look forward to seeing how you develop this.

My edit may not be better but my eyes at least find it easier to understand the shape of my ship. It's kind of flat, sloping down on certain edges.
Final advice: 90% of new pixel artists (definitely including myself) try to add too much detail and try to experiment with dithering on small surfaces to add shade or texture. In the end it becomes too noisy, the dithering doesn't really do anything and the shape is lost. That is always something to watch out for.
