Not trying to be mean or anything but sometimes it's better to be honest rather than try and sugar coat it... IMO the work shown on Behance isn't at a high enough standard to stand out, it's also 2 or more years old. Companies are basically able to pick and choose who they want to hire because graduate graphic designers are over saturated and there's also the rise of AI so they can save time etc. Put simply, I can find other graduates who show better work than you and will likely be just as cheap as you to hire.
The quality of the uploaded images are poor and it actually contradicts some of the text at the top about being detailed orientated. They're pixelated and as someone who does 3D design, the VR stuff is pretty low quality 3D work as well, if it was me I'd actually remove them.
What you probably need to do is get some personal projects done and upload them, remove all the date references on the work while you're at it. Your portfolio also kind of comes across as I still feel like a student and not as someone ready to work in design.
