The 'graphy area is for showing your 'stuff', feel free - you don't need to tout for business, if people like your stuff they will approach you.
I have been painting on computers almost non stop for 17 years or so, from some text thing on the Amstrad pcw8256, neopaint on the ST to Dpaint on the Amiga and PC then Photoshop etc with a Wacom tablet. I do some small things for people now and then, and so just like name-decals, I don't reallllllllly want people advertising stuff like that on here - but I don't mind people showing their stuff and selling themselves that way. If you know what I mean.
