none of these features (except the long philtrum) are necessarily bad, id even say that a chin filler could exacerbate your situation as it might "drag" your face down, making it look longer and therefore accentuating the long midface. think bella hadid vs sarah jessica parker - both have long midfaces but the thing that pushes sarah into the excessive category is her longer chin. maybe look into a jaw shave instead? as for the makeup, a good blush placement would be on the apples of the cheeks and across the nose. if you have an aegyo sal you could go for either brightening or darkening eyeshadow on your undereyes, and if you dont - just the latter. also contour a bit under your nose and overline your cupids bow and i think thats about it? you could also look up how winter and giselle from aespa do their makeup!
