So overall this consists highly of cool('cold') colours,leading roles played by blues of varied values and, maybe for balancy or else, for synthesis, purples slightly ascending and descending.(Interestinglypurple becomes the prima donna on first view)
It is usually not ideal using watercolor in portraits (abstract or realistic) instead of more 'sculptural' medias as oil. However she's successfully found out its own advantage: the comfortable effect, transparent, feather-like 'visual weight'. The face was shaped such that gives out relief and relax, and surely sub-conscious temptation and if any, a little blue emotion. Eyes like clear-water wells, flowers more than decorativation but also notes of atmospheric mood. Like this a lot.
