I joined ConceptArt.org and got myself gallery there.
There is sooooo much awesome work there to see!
Very inspiring, yes. Also many of the folks there are
working professionals on cutting edge stuff, so it's
useful to see what kind of work is getting business
and how good is "Good" right now.
I would highly encourage anybody interested in
illustration or concept art to check it out, since it's
free to join.
They have a very active forum as well, with all kinds
of up to the minute posts on current work and tutorials
and so on.
Here's my gallery there.
And the site's main page.
