To be really honest, it looks like crap.
- The detail difference between the spacship and the terrain is HUGE
- The spaceship looks like it fell into a barrel of car paint polish ( BUT, I like the retro design! Keep that style up! )
- The terrain is totally undetailed, just a flat piece with some random placed rocks. There is no variation in ground texture and the detail texture looks horrible.
- You could use a sprite shadow instead of dynamic shadows, they would look a lot better than the stencil ones.
- Some more variation on rock texture would do a good job
- The particles are too FPS consuming, rather try to make the particles bigger and use less, it also helps making it look more "solid" than a cheap source of sparks.
- The colors are generally totally washed out. More contrast would help a lot here.
Thats about the basic things I can tell. Anyway, i like the "style" but yet there is a lot to improve here before I call it nice
