Constructive criticisms are welcome :)

Funny feature you have there - “accessibility options”. Not sure it would be really useful for your visitors.
In your ‘Look, Cover, Write, Check’ test you should use longer words. I would try to make this test a bit “bigger” and more attractive. Your graphics is really bad IMHO.

I think the share this page (currently at the end of the page) should be moved to top-left of the site.  When I say “Top-Left”, the share buttons should align vertically to make unobtrusive for users.

I think this little change will do wonders for your site in terms of getting social mentions.
