Hi Neko,
A good start, technically. There are a few useful guidelines for flower shots, not that they must be followed,
a) Generally do not shoot down on flowers
b) Shoot them from their level or upwards
c) Do not place the centre of the flower in the centre of the image
d) Ensure you are focussed on the part that you wish to emphasise
e) Assess the background so that it will complement the subject
Looking at No 4 you could possibly have removed the stem of the other one close to it and isolated the flower more by getting in closer and chosen to have just the greenery or sky as the background, not both.

Thanks Grahame, I try to kepp in mind them.
But I couldn't understand the last point!
Can you tell simple? Sorry, my English is not so good.
e) Assess the background so that it will complement the subject
Another way to say this is that the background should not distract the viewer from the flower.
another, more general way to put Grahame's first two suggestions is this: don't shoot the flower from the same perspective that people walking by have. Try to find a different perspective. Often, that will not be looking down on the flower, but some times it can be. For example, here is one that fits Grahame's suggestion:
But here is one that is looking down, and I think it works fine, because it is an unusual perspective:
I will start with a quote from a review site "this is not a DSLR, don't expect DSLR results".
Flower photography is all about background...avoid clutter! Watch some of these...
