I'm trying to design a space ship, a fighter-sized ship for a game I'm thinking of.

This is just the early concept stuff here. This particular design was mostly made just free-form.
I appreciate any feedback or thoughts; what you like, what doesn't work, etc.

Well it's pretty early to tell what you're aiming for, but you've got an interesting shape to start with. I'm guessing the two groves/holes on the left and right are intakes of some kind?

What sort of concept are you going for? Are you trying to go retro, etc.? I currently get a bit of a retro feel. It can definitely work. A lot of it depends on what sort of detail you add.

A lot of things to think about going forward is how this spaceship would work. Does it have a cockpit? What kind of cockpit? What kind of thrusters? What kind of weapons? Where are these things located? Are they external or not? Things like that will definitely help as you design this craft.

I agree with the above comments that it looks too smooth. Add hard creases where you want to draw attention and where it would make sense if this was a real vehicle (take a look at some reference, to see where that might be.)

Not a huge fan of the bulging nosecone - too similar to a human nose, especially with the inlets acting as nostrils. I sense you don't want to make something comical, and this is heading in that direction (unless you did, in which case you need to push it further.)

Is this thing piloted or not? If it is, I'm not quite sure where he (or she) would sit, and what sort of visibility there might be, with a big nose in front and the big bulges in the fuselage in the back.

I know this is fiction, and these considerations can be ignored - this ship is very similar to the Vipers from Starship Galactica - but I like to think it adds another layer of interest to the world building.

If this thing is AI piloted? Some of the design choices make even less sense, if we look at the current developments in UCAV design.

Keep playing around with it, and good luck making something kick ass :D

I started over with a different design.

pretty cool looking. reminiscent of star wars designs. DId you know lucas based his designs and movement on ww2 fighters to make it easier for the audience to relate? makes for cool dog figting footage - but has nothing to do with reality. personally, i believe in form follows function. decide how the ship is supposed to work, then design a ship like that. tends to lead to more believable results. Much depends on the "look" you're going for: cool, cartoon, realistic, whatever.
