It will be great if add «no fab», or «no girl» filter which wont display any sexualized content. Without filter like that it becomes really difficult to find good artworks. I think that when you type «artwork» or «digital art» you shouldn't get results, where half of the images make more acsent rather on boobs than the idea itself. Tons of really good artworks where people put their hearts shouldn't be lost between hot girls.
Also I can't understand why when I search «fantasy artwork» I get some results which are non fantasy, non artwork as well.
