Needs a lot of work before you go to print...
1. Less photos.... A brochure is a way that a consumer can quickly and easily find out what you do. You don't want to include your entire image gallery showing what you do. But on the otherside, you don't want ALL text. Find a happy medium, and lay it out in a flowing design.
2. Lessen your use of fonts... 1-2 fonts TOPS.
3. Reduce the "ridged" feel.... a trifold brochure doesn't need to be exactly three panels on the inside... you could have it open up and be one full page.
4. Overall, this piece needs to be clear, and eye catching. Think to yourself, "if this is sitting in a brochure rack... (based on design alone, not subject) would I want to pick it up...."
There are some very professional looking brochures out there. You can either google some examples, or find your nearest brochure rack and find somethings you like and see what you come up with.
Hope that helps. Sorry if it's harsh, its all meant to be constructive.
