Hello.

If you are interested finding an artist I'd advise you to develop and nail down the gameplay aspects in first place and then build up commercial development scheme and search for an artist/composer/whatever after.

You simply spook away potential artist by saying that the game is in "embrional stage". You will make them question themselves "what i am working on then?" and in the end, most probably, it might end as a bad experience for both sides.

In short, develop the gameplay first (or at least make an illusion here on forum that its well developed) and then search for team members.
