Ahri Miyuko - painting practice

Just digital painting practice. I wanted to improve my style range to a more realist style. Decided to take a go with my favourite cosplayer, Spcats Miyuko (cosplaying Ahri from League of Legends)

It's my first portrait painting in a long time (don't ever remember if I ever did one, lol) so it isn't a very good one, and took a long time to draw too.
Any critique and feedback is much appreciated, I'm a noob at this photo-realism thingy m(_ _)m

No tracing, just photo reference

probably will do other painting half body (with other body parts and clothes) next ^^
