Hello Oliver, I put a number of tags on the article Willi Dreesen. Thank you for adding references and cleaning up the article, however, there's still a problem with notability. Notability on Wikipedia is sometimes a hard concept to understand, but every article on Wikipedia must indicate why the subject is notable. Sources that establish notability must be Third Party, quality and reliable and must discuss the subject in some amount of detail. So, reviews of his art or a major piece in a reputable book or magazine or online are good (in any language), listings from an Ausstellung is not. An article describing his impact on the local or international art scene is good, a blog post from a random fan saying the same thing is not. Anything directly controlled by the artist or his family can't be used for notability.

There's no need for a special section for notability. Statements to establish notability could look like this "Critic xxx of the yyy magazine said "Dreesen has reinvented the zzz genre..."<ref> text text </ref>

The other references that you have included are fine and establish that the Exhibitions occurred, but they don't establish notability.

If you have any questions, take a look at WP:ARTIST or leave a comment on my talk page.Tobyc75 (talk) 19:58, 26 September 2013 (UTC)Reply
