Design looks great, but makes everything tedious to read. Just show me information in a way which is pleasant to look at. Don't hit me over the head with your design. I get it, it is slick, but design should be enabling, not distracting.
Impressive design and effects, but that didn't help me to better understand the instructions. It was more of a distraction.
Great work - a bit of a 'form over function', but it at least got me till the end (which few how-tos do).
Well, the landing page is just awesome. Good work.
