I divided my portfolio into three sections, design, illustration and sketches. 
 Use the side navigation bar to go into the area you like to view. 
 
 DESIGN: This section is dedicated to ads, posters, logos
 and what have you.

 ILLUSTRATION: This section is dedicated to Clip art, graphic t's,
 technical drawings and other such pieces of art. 

 SKETCHES: This section is dedicated to Thumbnails, random thoughts
 and what ever is a work in progress 

 I do plan to add a couple more sections, such as Photos.
 But that is a little ways down the road
