Hey Madi,
If Wix’s functionality would allow for it, I would strongly suggest featuring links to your case studies on the home page – It’s the number 1 thing that visitors are coming to the site for.
Whether the above is possible via Wix or not, I would also, for the same purposes, rearrange your main navigation so that “Portfolio” is given more emphasis…so:
“Home - Portfolio - Resume - Blog - About Me”.
That reminds me…I have a dirty secret that will probably grose everyone out:
I like not having a “Home” link, and just making the logo a link to the home page instead – IF my audience is likely to consist of Design Agencies and recruiters.
Either way, this would probably depend, again, on Wix’s functionality.
Following on from that, likely the 2nd biggest Call to Action: “Contact Me”…My inclination would be to have “Contact Me” in the main navigation, after “About Me” ( And feel free to keep a copy of “Contact Me” in the footer, as is).
My final tip:
I mentioned “Design agencies and recruiters”…Run your site past them…Contact a recruiter, at least pretend that you’re coming to them to get your name on their records, and at the end of the conversation, ask them: “Any thoughts on my website?”.
Hope that helps. Good job so far 
EDIT: I just remembered, you did mention you were only after feedback on the portfolio section…My bad 
Just as well because Sarah Hawk actually said everything that I was gonna say about the case studies.
