Sorry to say so, but the use of inbuilt flash ruins the first photo for me. The shadows a way too sharp and the light in the background too quickly recedes into darkness only.
The same applies to the second photo, though the colours come out nicely here, but with regards to the second photo, it is the composition that bugs me. This photo screams for the scissors and says "Crop me so I look better!". The placement of the flower just now seems to be totally random, it only happened to show in the part of the frame where it does show, but it doesn't look like you planned for it to be there.
How much of the flowers did you actually see when you took these photos?
