i tend to agree with rev's suggestion to crop the top and left of the pic. i would place the centre of the flower at the bottom right third of the photo. the colours are deep and rich, with excellent detail in the water drops as well. definitely a good effort from a toy camera!
I would leave the picture as it is. Cropping to fulfil the 1/3 rule isn't essential, since the colour profile of the flower is contrasty enough to attract the attention. Nice job on the post-processing.
One thing that nags me though... the flower seems unnatural, with the far side showing more texture than the near side, or rather, the flower is neither uniformly flat (as in a bird-eye view flat), or textured enough to stand out.
What are your trying to show here ? There is no really dominat object to hang an eye ball on. There is much promise here youhave to decide what story you are telling. Its a very good capture and post processing you need to make hard decision on what is the story. I like this shot.
