Did you want any reference to actual blueprints?

We're not opposed to the blueprint reference. It's hard to say without seeing something. Generally speaking, we don't have a strong opinion either way at the moment but I'm sure that will change soon. One reason we wanted to use the site is that our vision of the logo is very open and could go in any number of directions. This seemed like a great opportunity to see a wide range of ideas. Hope that helps. Thanks for your interest!

can you please provide some feedback on my designs.
