I think the site could use a couple improvements: 1. The footer of the website has a totally different style than there rest of the website. 2. The header is not clear, there is a lot of wasted white space and I am not really sure how the plant is relevant in your product. Just my two cents.
I think the idea of your site is great but I would change a few things. The home page should be what your site is about, what service it is that you are providing. Then the things that you highlight like your works and your approach should be links that redirect them to those answers. Clients will click on these links if they want to see the information but I would recommend making your homepage very unique by creating your own personalized graphics that really shows off your talents. If the client doesn't like your homepage, chances are they are not going to read ANYTHING else on the site. Good luck.
