Well, maybe you should keep trying. I think your hand hand and your brain is not yet accustomed to drawing chaotically. More practice will allow for flexibility.
This is a very beautiful work of a mighty eagle. Do you have an online site where you sell your works?
that’s why I don’t know how to draw with a pen
Unfortunately I do not have these sites)
what sites are there?
Likewise me. I don't have any site but I know of a site a friend often display her works for sale - it is called "marketplace."
ok) thank you
