I have never designed promotional material, but I do a lot of software design, so take this with a grain of salt.
* The Word-Art font for the title definitely was the first thing that stuck out at me, and is indeed garish. I would want the front photo to be the first thing that catches my eye.
* The website on the front page seems out of place. It's almost like it's advertising people to go to your website rather than the showing.
* The colors on the front page seem a little strange. The photo has red on the top, blue/purple in the middle, and orange (reflection) on the bottom. I wonder if more closely matching the font colors to this image would make everything gel together nicely (such as making the title font red instead of the date/time red).
** Alternatively, you could stick with the same color for ALL fonts on the page.
* I think the alignment that paul mentions is a good observation. It's not bad to have right align in the middle block, but the text should be further from the image. Also, having "gallery" be a Widow word on the third line doesn't seem to flow correctly.
* The vertical alignment between blocks seems off.
I hope you don't mind, I took my ideas and created a quick mock-up of the front page. 
* Some of these ideas (like "gallery" being a widow word) could be applied to the back page
* Also on the back back, I'm not convinced you need the "Exhibit:" label |
