I using Flickr as my main personal showcase. My friend recommend me to try Deviantart cause there's more traditional artist here (Flickr is designed for photographer) and I remember I have deviant account from long time ago so i give it a try again, but it make me angry with all messy functions... Ended up del all olds image and not using this account anymore (they even say there's no canceling function).
If anyone interested in my drawing, visit: http://www.flickr.com/photos/foggyflute/
Flickr far more easy and useful for me.
