Here's something you need clarifying... It doesn't matter whether you claimed it to be yours or not! It is assumed to be yours, unless otherwise stated Also... whether it's made to make money or not, doesn't make a difference. And that's how copyright / plagiarism sees it. If you even use a logo or any content which is copied and pasted (that includes a logo), the source/author MUST be credited, in all cases. It can be a very major thing... but like I said... as it was your first project, imo the tutor should have had a word with you instead of putting it up the dean [surrender]
