Nice, I like the white theme.
I would say the following though:
1) Perhaps some of the content on the main page could use some fixes/changes? it's not obvious straight away what it is Pink Butterfly does until you start reading the content.
Perhaps start the content saying that Pink Butterfly is a wedding planning service then go on to say about how it was started etc.
But then i'd question if people would be that interested in knowing how it was started, is it really necessary to fill up the in your face content home page with information people might not be that bothered about?
I like to eat Subway for example but i'm not really that interested in how the Subway chains were started up
Perhaps you could ensure all this kind of info is available in the About section instead in case people want to dig deeper into the site?
2) The logo is almost screaming out for a logo image of a pink butterfly to go with it. You know one of those one/two tone filled images could look really good.
3) It may be a bit easier for reading the text if you don't have the patterned background going through the page content as well? I'd almost say to revervse the patterned/non patterned areas of the page that you have setup right now.
4) Generally your images work pretty well, but I don't think the picture of the Rolls Royce logo on the Contact Me page really works. Images imho should be somewhat relevant to the page topic/content to make sense!
5) Your contact form should have some kind of Captcha or similar, nothing too difficult, but it would stop people spamming your form. I find a simple 4 digit number Captcha works well.
Just some ideas/advice, take it or leave it, you/others may not agree with me but I don't believe in sugar coating things!
