Several have commented on the color scheme. I will throw in my 2 cents worth on the content.
Generally, shorter is better, especially online.
Make sure all pages support your Mission Statement in some way. I will have to admit I am getting a mixed message between the safety issues, Charlie’s love for cities, and sustainable/environmentally-friendly transportation. I’m not really sure what your main goal is.
On your main page, you state, “The CPI aims to support creative and environmentally sustainable initiatives that we think Charlie would have been proud of to create positive change in the Toronto community.” I would make the statement active by dropping the “aims to” because it makes you seem uncertain of your future. Take the position that you are doing what Charlie wanted: The CPI supports creative and environmentally sustainable initiatives to create positive change in the urban landscape."
At first glance, I thought the logo was done by a young child, perhaps Charlie himself. I then had a cognitive dissonance reaction (… The logo must be one of Charlie’s drawings … Charlie biked from San Diego to Toronto? … How old was this kid? … Oh, he was an adult.) In other words, the logo may actually be taking away from your message.
The top menu navigation is weird. Why is there a difference between Home and Back to CPI?
Some of the information is outdated. (The FreeWheels page needs to be re-written in the past tense, since it has all happened.)
Don’t make the visitors look for the Donate button … put it on every page. Try to establish a “touch” between the text on the page, the visitor’s heart, and the Donate button. Examples:
On the main page, try something like, “Join us in making cycling safer … Donate Now”.
On the About Charlie page, try something like, “Keep Charlie’s passion for sustainable transportation alive … Donate Now”.
On the Charlie’s FreeWheels page, try something like, “Help us sponsor tomorrow’s leaders in the cycling community … Donate Now”.
Again, the heartstring tagline needs to somehow refer to or support your Mission Statement, so that needs to be decided first.
