Ok... hope you right about the 'i take criticism well'... firstly:
-I dont like the logo, not sure whether you designed it but I dislike it.
- The top bar really doesn't fit and it looks awful... perhaps if you make it fit with the logo a bit more.
- text is too big, and bad font choice- looks like something out of a word processor
- dislike the nav bar at the side - it's ugly...
- dislike the layout , and the area on the home page with the blue circles - looks strange.
- home page should have some info on it instead on a navigation feature.
And there's probably more but that just a vague summary...
Hope that helps, and all the best with the project,
