Perfection in not a requirement for artists, just a little courage. A piece of artwork is the artist’s soul and to open the soul can be scary for the artist and sometimes for those viewing the work!
Every person who dares to take the time to be creative is bringing something new into the world. It does not matter if it is beautifully rendered or a little less so. Good art, great art and maybe not so great, ultimately there is only art. If it makes the creator of the work happy then there is a place for it in this world.
