How about your artists´signature?
Maybe a bit of a weird subject but not unimportant: Your artists´signature. Often enough you see something strange in one or another corner of a painting: too big, to obvious, too clumsy, too sloppy, etc, etc.
A signature conveys your intention. You are proud of what you have made and that expresses your signature. A sloppy text gives forth that you don´t take very seriously your own work; a too big signature tells something about the ego of the maker. (The worse the work, often the larger the signature.)
Be serious in every thing you do, so pay also attention to your signature.
