This is minor, but I don't think the umbrella icon makes sense for the "Small" plan given the constellation of craft that you use to illustrate the growing size of the larger plans. Perhaps a bicycle or a small compact car icon would do better?

I actually liked it - suggesting each one gives you a bit of lift, not speed. Unless you are Mary Poppins umbrellas won't get you very far.

Agreed. It doesn't fit in with the metaphor of the flying apparatuses (unless you are expecting Mary Poppins to sign up). I think a paper airplane would be a better placeholder, but that's the two cents of a non-designer.

If the metaphor refers to flying apparatuses, I vote for a cable car.
