Neetha, welcome to the macro / flora forum! I see you're using the Canon S2 - watch out...they have a tendency to make you want to sell your house and buy a DSLR. (I should know...I shot with an S3 for a year before taking the plunge!)
I like your image very much...you did a beautiful job on the composition - a good strong diagonal is there to guide the eye throughout. I like the different textures of the grass against the petals - nice touch! I do think overall it is a bit dark - if you have access to software you might try to bring the image up a bit more. I'd also consider cloning out the yellow bit in the lower right corner (LRC) so it doesn't take the eye away from the beautiful daisy.
Hey Neetha, welcome to macro/flora group, nice image, I like the strong light on the flower and nice dark BG. Agree with Jules on cloning the yellow spots,
