Presentation Criteria for a Visual Arts Extended Essay

I'm doing a Visual Arts EE.

I know in the marking criteria there is a "Presentation" criteria, where it states that to get the maximum mark (a 4, I think?) it needs to be "excellent". For other subjects, I'm pretty sure it just means that you have all the required sections/references, ie. Title page, abstract, bibliography, etc, as well as it being neat and logical. But in the art criterion (and since art is about aesthetics), it also suggests that a little more care in the presentation should be taken as well. What exactly does this mean?

Do I need to make a greater effort in making it look good? I have skills in graphic design, so that is no problem for me (if it needs to be done), but the thing I'm worried about is that this is a formal piece of scholarship. Would making it visually appealing (like to almost a well designed brochure, magazine, commercial design, etc. standard), as opposed to just a plain Times New Roman document, be detracting from the seriousness of the extended essay? Also, how appropriate is it to place a picture on the title page?

Last question... Is there a specific citation style that art essays need to use, eg. MLA, APA, Chicago, etc? Because I remember reading something about art essays having to use this one style.

Thanks so much!
