Nice shot!!!!
Here's a perspective from a full time professional wedding photographer. I never bring my professional equipment whenever I'm a guest at a wedding. There is an unwritten code between professional wedding photographers that we don't. It's tacky. Regardless if I like the work of the photographer of the day, as long as it is consistent with the photographer's portfolio and the bride and groom are aware of it. They hired the photographer for a reason, it's not really my place to take my equipment, get a few shots, then talk bad about another photographer's work. That is unprofessional behavior. If you do this full time for a living, you'd be annoyed to have to deal with guests at every wedding. The way I see it, if your work is good then let it speaks for itself. There is no need to put another's work down. Any one can grab a few lucky shots, only a few can tell the story of the day in an artistic and meaningful way... consistently.
Happy shooting!
