Hi, Euphony. I completely think that the simple outlines and shapes are getting more flowing and on the right track. But I still feel that the potential is really shining though. The good message, I think still you're getting a stronger idea on the lines of action and rhythm, but the strong message is that the lines of action could and would have been more boiled down to their rawer essences. Why don't you please free up your lines and hands with 16 minutes of 2 minute poses? (8 drawings)
The reason why you would and could do this is as a result, your lines and forms will be soon drawn more organic, flowing, but fully fluider. I feel that you're still gonna get this. For more info, please look into the Tonika Pantoja videos on YouTube about gesture drawing for art, cartooning, and animation.
Let's hope these can, shall, and will moreso work.
