First time being a second shooter

I have been asked once to do a wedding and did it. I was very hard and I want to do more but feel I want to practice first before going out there for real. Thank you Tami Webb a local photographer who has been doing this for 20 years. I was lucky enough to tag along with her on a wedding. This is my second wedding and here is what I have proofed so far. Man it was really tough to shoot a wedding. It makes me think if I really want to do it. But at the end of my long thinking I do. So here is my stuff from it. Let me know what you think. These are pictures of the flower girls taken while we are waiting for the bride to get dressed.
