The main thing to look at when you are making a site is:
[list=1][*]Can the person find the information they are after?[*]Do they need to search for information/navigation?[*]Is it laid out in a logical order?[*]Am I restricting the user in any way?[/list=1]
You should answer them
As long as you make the site user friendly and keep your colors/images reasonable, you should have no trouble.
I am doing a project, not on how to create a usable website, but about how different usability heuristics can conflict such as integrated help and support for beginners versus simplicity. I need the problems rather than the solutions
