I went to Kickstarter School and they advised consistently giving your backers updates. Allow for Q & A. Be in touch when they comment.
I wouldn't set a limit on your $25 rewards because they said $25 is the most often selected.
Is the goal you have set realistic? I mean, could you perchance get what you need done with $5,000 and then make a stretch goal to 8 and 10?
Before you go live, did you ask KS to review it? I think that is a good thing, too, to get advice directly from the horse's mouth.
Is there no video?
There's a lot of text in certain places...I would space it out with the pictures.
