You mentioned this being something for your portfolio after taking a UX course. Specifically, you’re asking for a critique on UX (user experience) rather than UI (user interface), right?
A UI critique would be easier since that would involve critiquing how your work looks, the personality it has and whether or not those things seemed appropriate to both the subject matter and the target audience. If that were the question, I’d have good things to say about your work.
However, a UX critique is much more difficult, in that you’re asking us to judge how well a user might experience the website based only on a series of static images. That’s a bit like asking people to critique a movie based on a handful of stills.
Just a note: I’m moving this and your other post to the student section. I hope that’s OK.
