Moan that the colours do not happen real realistically. For this reason is photograph in RAW usefully because one can adapt afterwards such corrections.
Furthermore the left shoulder of the model seems have over-exposed. Shorter exposure and/or smaller diaphragm (larger f number) could remedy this. Other solution is not in fuk sun on afternoon photograph hour, differently with parasol sun what screens.
This photo has a strange unnatural tinge that is especially noticeable in the blue looking grass (or what I assume is grass). Correcting this would I think improve the image quality.
