As far as I have seen, you haven’t yet posted a portfolio for review and feedback. This would be the very first thing to do to move forwards. In any case it would give you a baseline to work from, and still won’t stop you from moving industries if you wish.
I understand that it seems difficult to post your work if you don’t feel like your skills are good enough, but the feedback helps you to at least know what is and isn’t working. I’ve posted my portfolio a few times, and frankly they’ve been complete pieces of crap that, as it turns out, weren’t up to scratch and wouldn’t have gotten me a proper ID job, let alone the dream job.
However, it gave me a starting point to work from, and the feedback provided gave me some goals and helped motivate me to improve my skillset. I practise a lot in my own time now and will hopefully get into the right groove soon. Everything gained and nothing lost.
