Hey first, sorry to take that long to answer. It's been a very full of comments week :)

You are very welcome @enternamehere! It is really an honour to see that sharing these insights and that a few words can help, inspire or push others to go further =)

Yeah this whole thing about finishing is damn important, isn't it like when one do sports? I don't do much :D ... but all the effect it has on the body in facts takes place after the effort :) And indeed, like @winstonalden says, it doesn't need to be perfect, nonetheless as close as possible according to the creator's eye! Even if you can't publish it because you aren't that happy with it, your next one will be the bomb. Look at people who create "small" drawings, really fast, they usually have tons behind for a few that really kills it.
Also, even when satisfied, most of us will still find something unperfect to the artwork.

Thanks again for the motivating comment!
