Eh I don't know, I'm familiar with Sakimichans work, used to follow him/her (no idea there) but stopped years ago because everything he/she does looks so completly textureless. Back in art school we called works like this 'felt paintings', because everything has the exact same soft bland lighting and texture, like felt under a desk lamp. Not to mention in the case of sakimichan there are always positioning and composition problems... look at the angle of Ahris legs, then look at the width of her hips... are they not attached to each other? Right side of officer Vi as well, silhouette is completely lit yet you lose structure to poor positioning. Not to mention the regular sloppy perspective and cheap vignettes, seriously, stop vignetting everything!
Don't get me wrong he/she can do most everything better than I can do (though I'm working on that), and Riot has put out stuff with worse problems than anything in his or her gallery (coughnewkarmasplashcoughcough) but to say its so perfect that he or she should be hired on the spot is going a little far.
