you are doing great. When it comes to free handing it will never be "perfect" but that is the beauty of free hand drawing vs ai or using stencils. Now if you need a perfect circle by all means use a stencil. Any way one of the things that helps me is hovering my hand over the page and pantomiming the shape of a circle, not too fast not too slow, try to see your hand making the shape of a circle even try visualizing the circle and then when you are confident your hand is making the shape of a circle. keep the motion going but lower your pencil to the paper and keep the motion going, Remember, draw from the shoulder and elbow and understand when free hand drawing, no line is perfect, just work the multiple passes until it resembles a workable circle.

Trying to practice with shoulder and clockwise/counter-clockwise

This is great practice, keep it up!! Try the Mario Mushroom exercise right before this and then again right after a page like this, you'll see improvement in no time! https://www.proko.com/course-lesson/warmup-mushrooms

I still did the other exercises too. Big circles is my next focus, because I can’t seem to do them correctly. The bigger they get, the worse my lines look.

It’s okay if they’re not perfect circles! You want to put more emphasis on building the good habits than the outcome at this point. Using your whole arm instead of just your wrist is a big one here. This is a good low-risk exercise to help build that habit. That, ghosting your lines before you put them on the paper, and the follow through. Focusing on those things will naturally slow you down. The nice, symmetrical circles will follow!

this looks cool bro

I’m right handed when I write or draw and usually go counter clockwise starting at the top. But depending on the task I can switch between left and right pretty easily.
