The one thing you could work on a little bit more is going low and sitting on your punches a little more but that was already said. Good luck man.
When you turn pro, it is just another step on the journey. You aren't expected to be perfect or to know it all. You are just getting ready to start learning and testing yourself on a different level. I think you have potential, though there are certainly things you need to work on. But that is true of every fighter at any point in their career because you never finish learning or improving. Every time I watch one of your fights, and I have seen 6 now, I think, I get on you about your feet. If you can, find video of Roman Gonzalez, his most recent fight against Barrera, I think it was. In the first two rounds, he does what you do a lot of; he was very front foot heavy with his feet too far apart. But watch the way he shortens his stance from the 3rd round on, and how it affects his ability to punch harder, faster, and in combination. Best of luck.
