It's very nicely done, nice expression, pose & processing. The crit below is all minor so take it with a pinch of salt..
- Maybe the skin processing is a tiny bit overdone
- I'd tidy up some of the stray hair and liquify the bow so it isn't quite so quirky
- The lighting is nice but I'm not sure that this fairly moody & modern looking lighting style suits pin-up stuff. Flatter light and stronger colours are more common for this genre
- Similar, it's a smidge under-exposed for this genre - it's perfectly ok if that's what you were after, just doesn't look quite right to me. I'd boost the midtones a fair bit, add some pinkish tones to the highlights and maybe lift the black point too. I'd have a go but you've got edit images set to 'no'.
