Struggle to Find a Job - Honest Portfolio Review

I’m currently on a Graduate visa and looking for a Graphic Designer position in the UK. It’s been around a month since I started sending out applications again with my new portfolio website and updated CV, but I haven’t had any interviews yet. So far, I’ve sent around 40 applications, received 6 rejections, and the rest are either no replies or still waiting for responses. Before this, I was using a very general CV and portfolio, which didn’t work very well, so I spent some time improving them and making my portfolio more focused. I’m aware that my graphic design work may not be particularly outstanding, but I feel it should be industry-ready. I also understand that my multidisciplinary background in visual work has both pros and cons. Some areas have good potential, but I haven’t developed any one of them very deeply including graphic design (not as great as it should be). I spent quite a few years exploring what I’m passionate about, especially in film and art, so my experience has gone in different directions. I’m currently taking an online 3D lighting course, while looking for work in graphic design as this is where I have more professional experience and feel ready to work. But after months without any interviews I’m starting to feel a bit frustrated and wondering what I could improve. Any feedback on my portfolio, CV, or general approach would be really appreciated.
