Focus and depth of field: Focus is good, depth of field went a bit shallow, resulting in severe softness at the upper tip of the butterly's wing. You did a good job of isolating distracting background, but at the cost of the full sharpnes of the subject. A possible remedy is to either wait until the wings are in a flatter position to minimize the depth of field needed, or to take the picture from a different angle so that less depth of field is required.
A different angle would have hidden the bee, but I do not see the bee as a central player in this story. As it is the bee is partially hidden already.
Color saturation and hue are good. The yellows in the butterfly look a tiny but pale, but it could be that it is just the coloring of this insect. Brightness and contrast are done very well.
As this is an advanced editing challenge, I might have taken the opportunity to darken the light highlites in the background just a bit, to reduce distraction.
Well bravo - you resisted following all the rule of thirds and let the background supplement and guide the composition. Glad you resisted bumping the saturation level up too.
