Interesting portfolio, but which are physical? I can tell the rings are real because the font has jaggies that appear to be machining artefacts.

Keep in mind that even a free inexperienced worker costs a business money initially, so unless you find a training place times are hard as no one wants to lose money training someone who promptly jumps ship before they've paid back into the business what the business has invested in them.

My advice would to be get a job you can stomach to create income and start something of your own in your spare time, and work very hard on your USP!
