I like the idea behind this website, but the Home page is really loaded with stuff, try to cut the display of stuff by 1/3, the faster it loads the more pleasant it feels. Also try to light up the skin a little as a graphic designer for some tips on that. But as i said i like the idea of a how to do website with vids on it. Good luck with the website.
I think the site needs a bit more colour to it & possibly add a bit of design to the logo to make it stand out
