Good job!
Lovely colours and good detail on the petals and stamen.
I assume this was taken with the on-board flash, as the flower petals and other flower heads are brightly and evenly lit. If that's the case, most of the light captured here appears to be from the flash. Something you might try as an experiment next time is to increase the ISO (to 200 or even 400). By increasing the sensitivity, the flash output won't need to be as strong, and you'll get more of a balance between natural and flash lighting. The downside with using the higher ISO is that the image will be noisier, but that may not matter too much. Give it a whirl and see if you notice the different effect
As a side note, I really like the F 28-80 lens... it renders out-of-focus areas very nicely when used like this.
