Congrats on taking that step! It's a good start. I'd make the call to action (CTA) clearer. Also, clicking on the "book a free 1:1" doesn't go anywhere.
Linktree is good if you have a bunch of sites that you want to highlight. I find Carrd to be sleeker, more professional, and better with icons. I'm a big visual person so I prefer seeing an image of something I'm familiar with and clicking. Linktree is more text-heavy.
