Hey there! According to the Pokemon settei page on psartroom.weebly.com, I noticed the concept art for Gen 7 stuff weren't added yet. Those being the 7 UBs, Rowlet/Popplio/Litten, Solgaleo/Lunala, Necrozma, the 4 Tapus, Alolan Raichu, Alolan Exeggutor, Zygarde 10% Forme, and I guess Rotom Pokedex.
Do you plan on adding them, and if so, would you need help finding the concept art? I can provide them for you if so.
