I like that and I think practice is great.
It is hard for me to find a balance between practice and being productive.
In music it´s easier for me because I play in a very primitive style and playing
shows, recording songs, rehearsing with the bands, writing songs is being
productive & practice in one. It´s all fun and you get better at your instrument.
I haven´t found something like that for drawing comics. Studying, doing line
warm ups etc is no fun and it leads to a burn out when I do it too much.
Drawing comics or characters is not as effective as studying anatomy.
The amount of theoretical knowledge is just bigger than it is in making music,
at least in my case
