Am trying to learn about the arm but i feel like im going about learning wrong, in the sense of how i am going about trying to understanding is bad. Like trying to make every step of the process look neat even though it keeps coming out into a cobbled mess and i feel like im wasting wayy to much time trying to do so. I feel like im going so very slow. Like in the time i did 4 arms i should have made at least 16 in an hour or even more but if i go too fast i feel like im just gonna push out half assed shit without understanding. Espically trying to get the cylinders right. In addition im wondering if i am drawing too small again and is hurting my understanding and speed. Like the very bottom arm is only 7cm long.
