Hi Luke,
If these are for a hair and make-up portfolio, you’d want to be getting in closer and showing if off.
Theres a bit of an issue with sharpness in these, mainly the first one and you need to get some light in the eyes and across the face to bring out her features. Would be worth investing in a flash if you don’t have one.
The white balance and colour could do with tweaking also.
Fair play to you getting out there and being imaginative though. Nice model too.
