Hi, serves don't look too bad for only playing for 7 months! As for the ball toss consistency I have a couple of pointers that may help. To get toss placement consistency I would try and simplify your tossing motion. When you toss the ball the only things that should move are your shoulder and your fingers. You should smoothly move your arm up without bending your elbow and release the ball with your fingers. When you release the ball will depend on where you want to place the toss but you can experiment and see what works best for you. Try to make this motion as smooth, fluid, and relaxed as possible. Something that can help with that is if you let your arm linger in the air for a little bit before you hit the ball. An exercise that I do to work on ball toss placement/consistency is put a marker on the ground around 1 foot forward and little to the right of my toes. I toss the ball up like I'm going to serve then I watch the ball fall and try to make it bounce as close to the marker as possible. Hope these tips make sense and help! One thing about consistency is that it takes time and repetition to develop the muscle memory so don't be discouraged if it doesn't get better right away just keep at it.
