/3/ - 3DCG

I'm 22 is my portfolio I made. I know this is really embarrassing, that it is not appropriate at all for this job. I wanted to try to make things inspired by fortnite, but I hope this tells more of the actual issues I have now whether i know them or not. I don’t have a good enough idea of what I am supposed to do, and at the time of making them I thought that these artworks were supposed to be appropriate with what I was supposed to learn before, I didn’t use any references for them because I thought I was supposed to to know how things looked with a good visual library, but it’s not how it works and I’m not sure when I’m supposed to make things up or take from a reference. In general I’m not sure of where I use a reference and where do I have to not use one. It’s just confusing because I really don’t have anyone in my area that I could talk to about this. I don’t really have social medias and it’s really difficult trying to think of what I’m supposed to learn and how am I and how I’m supposed to use it at the work environment. Is the reference I need supposed to be blender? Can I just download any human body model to draw over, and environments too?Because I can navigate through it to do it.
I want to learn the right way to do this so I can be a reliable and professional person for this job.
