There's something lovely about yellow and blue like this. Something kind of funky around the edges of the flowers though. I suspect to do with the brightness
These yellowish and bluish colors are great and it makes the picture a little bit artistic. I think you were too close to the subject with f1.2. I would recommend to close aperture a little bit (e.g.: f2.8) or take a step back and crop the picture next time. However this lens has nice bokeh.
