Great to see you in the community! I’m glad to hear you want to start practicing more. Even 10 minutes can make a big difference.
There are a couple things I can recommend for your left hand pinkey without actually seeing your hand. First: make sure your wrist is staying straight. Then, check that when you put your fingers down on the fingerboard, they all stand tall and square. Try drilling your pinkey very slowly. I would start on the A string putting down one finger at a time and then lifting them up one at a time. A-1-2-3-4-3-2-1-A. Once you put a finger down keep it down until it is time to lift it. So when you put down your pinky, 1,2,&3 will still be on the fingerboard. Once you are able to do this exercise several times in a row keeping each finger on its tip, then move on to A-1-2-3 4-3-4-3 4-3-4-3 4-3-2-1-A. You can do these with or with out the bow. Start slowly!
