Until I get some time/energy over for the planed English version or some languageclasses, I suggest:

http://www.dargaud.com/site_valerian/  (publishers site + links for ordering! French)

http://www.noosfere.org/mezieres/pages/actu/actuanglais.htm (a bit mixed both French and English)

http://fraphael.free.fr/Valerian_index.htm (French site)

http://www.coolfrenchcomics.com/valerian.htm (English site)

You can still send in fan art to Point Central though, they will be published here for all to see. :)
