The diorama has dust on it. I just am okay with it. I sometimes have to clear it from the water tiles/rivers, but it does not bother me much. If I left it out for multiple years, the dust might reach unacceptable levels, and I will certainly attempt to clean it then.
Yes, I am a collector of miniature art who enjoys putting together dioramas and interesting, dynamic miniature scenes. That is my hobby, and I really enjoy it. And I can help encourage artists by commissioning them to paint for me. I only select the very best artists to paint for me as I am quite discerning. Both Bohun and Sebastian are my favorite, but I am also exploring others who are very, very talented as well (e.g., Alexi-Z, Ana, JBT, Lukasz Grzyb, Robert Carlsson, Michal Pisarski, Nakatan, etc.). I should note that, aside from artistic ability, I also value professionalism, consistent delivery of high quality paint jobs, and meeting of internal deadlines without sacrificing quality. An artist can be very, very good, but if they take forever to complete my models and miss repeated deadlines, I find myself less enthused about using them again in the future.
On that note - here are some barbarians painted by Lukasz Grzyb of FantasyGames
