First attempt at photography

I went to the flower conservatory in San Fransisco on wednesday and decided to be the family photographer. i think they turned out pretty good for the first time i really picked the camera up. Dont bother looking at the bigger pictures,they look like crap, especially the Day Lilly one, i tried to sharpen it since it was a little out of focus. any ways go here/!

Please C&C it, i think i might start taking more pictures and i will probably need advice.

The only crit i cn see is that there is not enough light on the second photo (Day lilly).

Yeah, that isnt one of my favorite pictures.I just added two more that were in my back yard.
