Hello SpiritRetro and welcome!
Losing yourself in a good drawing is such a great sensation, and it gets even better as you progress over time. Your starting sketches are great, with good appeal and proportions. You're in the right place to learn and showcase your progression. I also recommend you check out the Discord server (I think this link will work: https://discord.gg/vYY7hCg ), which is significantly more active and alive than the forums here.
Finally, the structure here is that we always update the same forum post over and over with new artwork instead of making new posts for new terms. I recommend you change your post's name to "SpiritRetro - Art School journey" instead of "starting point sketches", because that title may not be so relevant in the future.
Once again, welcome, and I hope you enjoy it here!
Cheers!
