The first question you have to ask yourself is how functional your home page title is. How many people will do a search on 'WD Webmasters - Premium Website Templates'
And, more to the point, take your meta description - who will search on 'Welcome to the most complete template library! More than 8000 for you to chose'
Then, your first indexible text is in you H1 tag. Again, you have repeated a term which is unlikely to be very high in the list of most likely search terms.

Your next text, 'Our company offers its customers a great variety of products. Everything you need can be found in this site.' is completely lacking in any keywords.

All I can suggest is that you go back to the drawing board as regards evaluating your keywords and their position on the page. You show some good beginnings. Now you just need to add some value so that the search engines can know what the page is about.
