What a nice overview of your game, that is definitely a nice start.

I am not sure how much your trying to get in funding but huge amounts (above $125k) are very hard to attain unless your like an existing IP or your have a lot of name recognition. When you sit back and look at it Elite: Dangerous didn't even blow the doors off its funding goal and this game IP has a huge following for its previous three games. My advise aim for what you absolutely need to finish the project by the date you have set.

I can stress this more, post on your kickstarter, screenshots, videos, answer questions from people funding etc... show that you are a active developer and your passionate about your game and the potential buyers will be able to see that.

Personally in recent years there has been a lot of space game kickstarters so is there a saturation of these projects? Also something to consider when coming up with a funding goal.

But looking good and those models are amazing and the whole open source modeling is great!
