They're a start. I would suggest concentrating on your framing and exposure. Try and get closer in to the bloom/stem and avoid excess emtpy space such as you have in #s 1 & 2. Watch your background and avoid bright areas, such as #2 which will upset your exposure.
Alright, I tryed to get as close as I could to my subject. I was using the 50mm so it doesn't like to focus too close. I guess I could of cropped them down alittle bit.
Man your lucky your in utah, I'm sure there are soo many more things to photograph.
