I often am a browser at times and can just spend hours on end looking at the many galleries on Epilogue - The Fantasy And Sci-Fi Art Gallery To look at other fantasy art is the most inspirational thing any artist can do. Of course just like Elfwood there are a mix of professional artists and just fans of the genre but as an artists I believe we can learn from the art of anyone, professional or not.
As you'll find new ideas in the strangest of places, take Youtube for example there are various videos which are from excellent artists and then from people whose drawing may not be perceived as good, but I say rubbish, the very fact that any artist is having a go means they are celebrating the fact that they love the art form of fantasy art and that is good enough for me and inspiring to watch no matter what the result turns out like.
The good and well intentioned forum users in the Epilogue forum entitled The Common Room is a fabulous place to see others work unfinished or not and to discuss each others work.
In addition to the fantasy art forums there is a tutorial section that goes through many things any artist might need to know about certain things like selling your fantasy art on Ebay or commissioning art and many more helpful resource articles.
So if you are into the mechanics of fantasy art and want an extra outlet for your work then Epilogue is a friendly place to get to know other artists and highly recommend getting to know people there.
