Yes, do follow ups. Most of the time when I get responses from people they are pleased to hear that I am interested in their project.
If you want to know those answers the only way to get them is ask. If they tell you that you didn't get the job don't be afraid to ask why not. Most of the times it will be price. Since most people assume apples to apples therefore the lower price is the better deal. So if there answer IS price then ask them where you were in the price range of their estimates and if your bold ask the price they went with.
Sometimes it's just an interaction problem with getting a job, they liked so and so better than you, it happens.
