Hi all. I've read carefully all your post. I have to say that as Undead suggested, gameplay should weight a lot more. You can have an "ugly" map but as long as it is fun to play, people will play it (which is the main aim at the end of the day). This is not true the other way round though. Mousikos gave a very good idea on which we can work.
However, As a teacher I can only demand clearer criteria. For example, how are you evaluating lightening? You need to be as objective as possible and stick to a clear evaluating rubric known by everybody. Doing this, you will avoid judging "oh, I like it. 3 points" or "oh, it's good. 2 points" for further questions about evaluation, just pm me. I can guide you on it.
