Arms and hands are rather difficult, in fact i would say they are the hardest to draw. (or at least for me) Drawing arms can become repetitive after awhile that is true! but never tedious! things only become tedious if you are already good at them. Art has no exact answer, no perfect piece! so practice, practice and practice! and never think of it as being tedious!
On top of that i always knew the term "practice makes perfect", but i have come to realize whoever said that sentence for the first time, yeah, probably an artist. I have started this rigorous sketching "boot camp" of really getting cracking! Get some work done! and none of that fluffy, draw your emotions stuff! This is art as a business! Practice, improve, repeat! I have already seen improvements in my own work, and that makes me happy!
Without further a due!
Everyone enjoy the beginning of spring!
