Glad you like them and think it is a good topic^^
Making a comic would be awesome... But I would not use humanoid mazzelhs for that, as I don't think I have the discipline required to keep drawing those as many time as needed for a comic.
I started drawing when I could hold a crayon and move it around on a receptive surface. It hasn't really jumped off into being a career for me yet, though drawing is the line of work I hope to get into (possibly via animation).
How to work around the frustration? First of all, accept that you are not as good as you would like to be. You never will be, there will always be someone who are better than you. Do not get discouraged by this! Believe in your own skills, and keep practicing. If an idea you had doesn't turn out as you wanted it, try again!
But if something frustrates you too much, try drawing something else.
Art time!
Did you know all fullgrown mazzelhs and many young adults have the ability to curl into fluffballs? It's true! Some of them even manage to pull their tail in too.
