i think it can look cute, I’m 31 and I do a similar look sometimes when I need a flush of colour on my face. I think the issue is she does it in the way that the super young girls do it where they do a streak of blush across their cheeks and nose, rather than a light flush of colour. The way the young girls do it is very much like an anime charchter (including the drawn on lashes) but if you want to look a bit more grown up but still cute a soft swipe of the colour makes you look like you’ve caught the sun.
I’ve been watching a few of her videos today and whilst I think she’s likely a nice girl she really can’t do her makeup - that’s not a criticism it’s just a statement. I think she’s got a lot of potential but she’s stuck in a rut and likely a little nervous about her age. Also she’s been with the same person since she was what? 16? No proposal, no children, no nice holidays together? Not that everyone HAS to do those things but it seems like their relationship hasn’t progressed since their teens, okay they have the house but have they actually done anything with it? She feels like she’s stuck at about 22.
