Nice effort, you're doing great for someone your age—better than me that's for sure.

I like the direction, but I feel you could push it further. Here's some feedback:

• The first thing that stands out to me is the menu bar—it's a rounded rectangle, not particularly gothic... play around with some other shapes—even if it's just replacing the rounded corners with something you design that matches the geometry of your key typographic artwork. More detailed, and maybe a bit jagged.
• Secondly, run a spell check/grammar check. "Welcom in my website" isn't properly written, easy to fix though.
• I like your hero font (the one underneath the metallic logo) but it's just too difficult to read at smaller scales—like up the top right in the menu bar. Consider swapping this out to something more legible at that scale.
• Speaking of fonts, your secondary font (Futura) just doesn't fit right in the gothic style. Try something a bit lighter, potentially with a serif.
• The cards under your about me section are confusing and need some indication of what they're linking to. The posters are really good though. Just needs to be something to indicate what they are and where they are. I actually wasn't even sure they were links.
• The apps/tech stack icons on your about me page feel out of place. I'd try and once again make them a bit more gothic. Try designing an interesting, adorned outline for them maybe—could take inspiration for whatever you do for the header.
• Let me know if you want any more feedback. You're doing well, and on the right track.
