I would never forget this art style, this is a nekodanshaku work, i hope that doesn't mean he stopped doing doujinshis tho.
I feel a bit divided on this one, it seems like a good premisse of a loli helping the mangaka by using her naturally alluring body while she learns how to draw manga, but the issue is that since it's a manga we know they will sadly never go all the way, nor will they show much more than what was shown now, keeping only in the teasing zone, i doubt we will even see an uncensored nipple, i mean, it's still hot but knowing all the artist's potential it does sound like a bit of a waste imo
