Thank you for your advices.
I do have a hard time focusing on the line of action :( I am going to train that without time limit first.
I will be back with more drawings soon :)
Thank you for your response !
I certainly will try a figure study in 20 minutes soon !
I didn't know about line-speed-beauty before, but I just checked on the Internet. So I have to work on doing perfect studies, then make them perfect and quick, and then add my artistic touch, is that it ?
