Hey!
I spotted some problems:
- typography
- slider is WAY TOO SIMPLE
- navigation bar needs to be improved a bit
- there are problems about spacing (took About body as example. You have to work a bit more on it)
- colors and contrast (how about new colors? Let me help you: HERE)
- heading aren’t really responsive… check for that
- you have tried to add a image header to some pages… Well, for some the image is very big and disturbing. Also, a text on them won’t be bad.
- try to merge some css files. Some of them should be merged.
- create a more intuitive and simple coding of your theme. HTML document looks a bit wierdo for me and I lose my atention in your document. Try to add more spacing, a [TAB] for every new tag in another
Hope you will solve something. Anyway, it has a nice idea at the base. Good luck!
