Review my mockup tool: WireframeSketcher
nathan82: The tour pages are really well put together content wise; When trying to decide if a program is worth a downloading, I usually scan the screenshots page and make a quick decision based on first impressions. Comes across as easy to use but with some nice power features.The landing page screenshot has been poorly resized however. I'd make that a bit bigger and prettier, and you could even go so far as adding slick little javascript tooltips to explain different tools. Could help your conversion rates maybe? Also perhaps consider using the same shiny green 'Try It Now' button on the bottom of the tour pages, instead of switching to a text link. Small grammar nitpick, 'How it works' is not a question.
