I thought that I had commented earlier, but since I hadn't, I'll do so now: fascinating concept... I really like it! I can't wait to see where it's going to lead.

You commented that you had been critiqued on DA for giving measurements... whoever did so deserves to be critiqued themselves for giving bad advice! There is nothing wrong with providing basic info to assist the reader in his/her visualization of your story. Anything that helps the reader to understand your story, without interrupting the flow of the story, is eminantly acceptable.

Keep up the good work, and stick with it. I do recommend getting more familiar with the metric system, if you intend to use it... and don't mix metric and english measurements in the same paragraph. It's too easy to confuse what you are saying. Otherwise, come on back and continue your story!

Wow. Your attention to detail is awesome. Please don't stop. Your grammer was fine by the way, nothing major or obvious.
