WOW! Nature is full of beautiful surprises isnt it? I think the high key BG helps bring out the colors much better. The melting of the OOF dews draws the viewers gradually into the whiteness and makes the transition from color to white smooth. The presence of the spider is a bonus.
Its a nice thing the dew runs diagnoally across the frame and the 1/3 placement of the spider, while conforming to the rules of photography add a nice feel.
