Is this art appropriate to submit in my portfolio?

Hello, I’m new here so please forgive me if I do this wrong. I’ve scoured the forums looking for a thread like mine but haven’t found anything.

I am submitting an art portfolio to the following schools: Amherst College, Pomona College, and Duke University, however I am NOT applying as an art major. I have many different pieces in my portfolio including traditional media pieces and digital pieces, all of which are complete and high quality.

However, a large chunk of my “artistic career” is character designing. From 2011-2013 I ran an online character design business in which I created unique character designs and sold the rights to them under the alias saygo-pohm on deviantart,com. Is something like this appropriate to include in my portfolio? Some of my best work: http://fav.me/d62jq4z http://fav.me/d62gaow

The reason I am concerned about appropriateness is because some colleges like Duke specifically say “you should not include Manga or cartooning in your fine art portfolio,” and while my art isn’t exactly manga it borrows stylistic elements from it.

Thank you in advance for your feedback

It does look like what they are referring to…

But can you include the link in your “activities” as a business?

My activities list in my commonapp are already completely full!

Additional info!

This looks just like manga to me. Err on the side of caution, leave it out. You say your portfolio has quality work in it, so submit that.
