I visited the Meuseum, and the Curator asked me, that if I met anyone with a painting, to persuade them to put it in the upper floor, how do I do that, and where are these artists.
At first, there is nothing on this floor. However, in Pokémon Ruby, Sapphire, and Emerald, if the player wins a Master Rank Pokémon Contest with at least 800 points, an artist will approach the player saying he's done a painting that might even look good in a museum, at which point the player will direct him to the Lilycove Museum. If the player accrues five paintings, one for each Contest category, the curator will give the player a Glass Ornament for their Secret Base. In Pokémon Omega Ruby and Alpha Sapphire, each category has three frames, one of which will be filled each time the player wins a Master Rank Contest. Once all frames have been filled, the curator will give the player the Glass Ornament if talked to.
I believe you have to beat the challenges in master rank with a score over 800 to get the paintings.
