Could the seniors here give me some pointers regarding my portfolio and resume? Perhaps this is off-topic but what kind of related work could I do to sustain myself while I sharpen my skills and work on my projects?
first thing that comes up to me is there is no focus, theres a game, some models, multiple programming languages, etc.
what kind of job are you applying for?
you have a lot of different skillset so it would be best to focus on the thing you like doing the most and cater your portfolio and cv towards that.
