In order for your project to sell, you need to learn how to communicate with your visitors and potential customers. Who you are, what are you offering, and what are you trying to accomplish - this type of information really should not be left out. Also if you have a Contact page on your website (with your email, phone number, etc.), you can write such a text right there. Or you can take one step further.
If you for example don't want to add only a slideshow or a presentation of your galleries to the homepage, but you want to address your customers in a more original manner, you can write your welcoming text right on the homepage. This will be appreciated not only by your customers, but also by the Internet search engines.
Finally, if you really do create such a text, either for the Contact/About page or on your homepage (however do not duplicate this text for more than one use), it should also contain a picture, preferably your own portrait, plus a specific example of your work.
