My first website. Any suggestion?

First looks great! Secondly always nice to "meet" a fellow Brit!

I would say the next thing on your list would be security headers. The second I saw "cybersecurity enthusiast" as your headline that is what I jumped on to check!

Check out the Mozilla observatory score for your site - it doesn't score well (yet!)

Also along the same lines you are using a version of jQuery with known vulnerabilities so update to 3.5.1 and a similar issue with bootstrap so update that!

Fix those if you are going to promote cyber security as a passion as it isn't something I would immediately check on a site but you prompted me to do so!

Looks pretty nice!

My only remark is: when you hover one of the skills (in the 'Skills' section), the colour changes progressively which isn't the case when your cursor stops hovering.
For instance:

I find the transition back to the original colour a bit abrupt.

I don't think the design needs more polishing, but if you'd serve more responsive images in .webp you could gain 4.20s on first page load (that's big). Lighthouse analysis gave me a few more tips on how you could improve perf and accessibility.

This is a really great site. I can tell that you listened to feedback from you previous post. I have one suggestion. Adding an arbitrary rating to your skills is generally not advantages for you. The rational is that people will look at a two star rating for a skill and interpret it differently. Generally, you want your projects to demonstrate your skills and if asked, you say how many years experience you have with a technology. Basically what I am saying is "show don't tell." On your site, I recommend removing the star ratings and just listing the technologies as is.

Maybe you can add more hover effects, like on titles, on your name, or on social icons?

Also I think you should add <meta property="og:*"> tags which would allow you to precisely control how this link would look like as shared on social medias.
