PLEASE ANYBODY WHO CAN DRAW ART OR MORE SPECIFICALLY PORTRAITS REPLY TO THIS

Ok so, as i have already said, I used to use ai, but now that I am no longer going to use both ai to make bots or ai to make images, I would like some tips on how to make portraits digitally or traditionally, whichever it is doesnt matter, though I prefer traditional artistry. This is because I have a few OC's which I would like to make bots of, though I cannot currently draw very well, and would like to improve the quality of my art before using it as a profile picture on a bot, since my bots from now will be much more effort pit into them, I also want the pictures to reflect this.
