The images you have for each project are pretty solid outside of some minor edits (especially the sketches, big fan of your drawing style), but you need to format them. Each page needs to be curated. However, I'd start by organizing your portfolio overall. You need a cover page, table of contents, some way of organizing your work to be a cohesive collection vs an eclectic grouping of studio projects.

Do you have any examples of this that you can share?

I agree with what ham1 stated above. The portfolio can use some curating on each page, maybe some more white space, and the photos of the models could maybe be decreased. One photo may be more powerful than a combination of 3-6. 

Try looking at Issuu for examples of portfolios and how they use white space/curate each page. Especially along the inner spine, I think having full bleed images is definitely a route to take but that needs to be intentional. Sometimes its best to leave some breathing room between the two pages. 

I like your purple and red drawing style a lot though, the axons shine most out of all the images for me!
