Website feedback - specifically on gallery and credits pages

Site URL: http://www.whittakerchoreography.com

I've been updating my website and would love to get some feedback on the new layout. I have concerns over the gallery & credits page, I think they maybe over crowded and there is potentially a way I could consolidate them into one page but before I commit to doing that I wanted to gage peoples opinions. 

Opinions on full website welcome, many thanks 

I think the homepage is essential but tells me almost nothing
