I would start by stretching the sections to be the width of the page. Right now, it has a bit of an awkward size where everything is centred and both sides of are white. It just looks like an old website that isn’t responsive.
I don’t feel like the hero image best represents what you offer. I just don’t understand what the image is supposed to portray.
The form is fine, I do fine the age range a little awkward. 0-44? are parents doing this for their children? If you are 16 can you do this for yourself? If you are underage do you need a parents consent?
The “get a quote” button at the bottom of the page doesn’t have any script or anything on it - when you click it, it doesn’t scroll you up to the form or open a lightbox. It just appears to be a button that doesn’t do anything.
I would space out the sections just a little bit more. Maybe even try some false bottom/angled section. Right now, I just feel like there is a lot of information very closely stacked together.
Favicon, to build trust before your page even loads.
You’re on the right track!!
