Is my site layout saveable?

Two years ago I made a custom layout for my website. At a small scale it worked perfectly (only one page) but now the site is hard to navigate, the layout looks esoteric and there are too much elements (see the projects). I tried fixing it with making the background less bright and vibrant but I find that the site is still unpleasant to navigate. My question is: Should I make a complete style rework or can I fix the current style to make it more accessible?

Here is the site: https://afghangoat.hu

Any feedback is appreciated!
