Adding in a banner

I added in a banner and instantly knew that I didn't feel as though it fitted. I now feel as though there is too much yellow on the page, and I need to reduce that in order to highlight the really important information (hopefully just the bits that use buzz-words). 

I also asked my teacher's advice on the banner and she remarked that it didn't look professional enough. She suggested that the text font was also too simple, which I already knew but it was good to get confirmation. She also said that I should maybe create a sort of outline for the banner to make it look more professional.

From my own reflection the banner is too straight and boring. I need to add some character to it.
