Simple nice and clean, and of course straight to where they can contact you. Its a good start for sure. One thing that has been mentioned in recent workshops (from other designers as well) is if you're a one man show, be transparent about it.
If you're interested, check the workshop that @PixelGeek did with Michael Locke.
Lots of valuable tips. Other than that, start your own fictitious projects so that you can show what you are able to do.
Another thing you can start doing is messing around with Webflow as you are right now. Creating prototypes of (fictitious projects) or simply starting with prompts from http://www.dailyui.com in any Design Platform you use and then recreating it in Webflow with animations, which in return allows you to also share in your portfolio.
Other things that comes to mind is as you continue progressing, you can start making videos of you creating a website in Webflow or simple recreation of Designs in Webflow (which I will be doing in this week or next week, waiting for my microphone)
Just sharing some other thoughts that came to mind, that can help with building up your experience.
