Keep practicing +1. It takes time even just to get used to working from a tablet. Be patient and know that with each practice you do you're getting better. However, with each day you take off practice you slip backwards a little. There is no stagnation, there is always a force pushing you somewhere - whether that's your force, or the force of natural decay (of skill).
Yup. Good first attempts, though. To clean up your line work, drop the opacity, create a new layer, and make another pass, except this time a little tighter. Repeat as necessary. Keep going!
