I do not write critiques usually as I am not good in that part probably, but don't want to leave this one without a word. At first it looks like another cosplay model photo and in fact it is on the surface. If You take a closer look You'll see the difference, some details that made me to love this shot.
Posed but not exactly - it is a bit candid, I mean spontaneous in posing - and that makes it more natural. Colours are nicely spread in the composition, red and blue co-operate well, yellowish blonde hair accent sets the balance. About a model - love her face, not here only, check the gallery, photos differ with the same person on them. Freckles she bears on her face are just lovely. I could say how much I adore her legs and this sexy part of uncovered body but it would be rated 18+ so lets stay with what I already wrote. Beautiful model, nice composition and colours.
Technically You may say this cut legs (hip/foot) is wrong but I take it as a fashion-like portrait in a bit old American style cropping
