Get rid of the AI profile picture. Just use the picture on your resume! That AI one means a good chunk of people will hate this website before they even click your name to "login" due to their own preexisting biases. As an artist myself I'm not happy about how AI companies have shamelessly plagiarized people's work. The fact you're using the same Studio Ghibli style everyone else is using just feels unoriginal. Whether employers would care is another story entirely.

Others have left good feedback regarding the UI inconsistencies that you should address.

If you really want this to reflect on your abilities as a graphic designer, you should make this "themeable." XP had multiple visual styles - there were variants of Luna, as well as the Royale theme that came with Media Center Edition, and other themes like the Zune theme. There were also numerous third-party user-created themes you could download and use (if you installed a dll patch).

You should consider adding a few of the standard themes - at the very least the silver, olive, and royale themes. But more importantly, you should make your own themes, and add them as options as well. Open up a dialog similar to XP's "Appearance" dialog on first run so users instantly know they will have that option.

It's great if you can recreate a user interface... but anyone can do that and many already have. What matters more is how you can build on the UI while remaining true to its design language and interaction paradigms. What uniqueness can you add to the UI?

Here are some links for inspiration:

- One example of this sort of thing is https://macthemes.garden/, which has thousands of Mac OS 8/9 themes.

- Here's the wikipedia article that goes over the first party XP themes: https://en.wikipedia.org/wiki/Windows_XP_visual_styles

- For examples of XP third party themes... I don't know any good websites off the top of my head but DeviantArt has had lots of 3rd party themes and style assets uploaded to it over the years (for both Windows and macOS): https://www.deviantart.com/search?q=windows+xp+themes

Use these as inspiration and come up with your own unique visual styles which would still feel at home with Windows XP. If you can do that, I think it will really impress people.
