Art as an EC for selective colleges?

<p>Hi, I'm new to CC so please excuse me if I'm posting in the wrong place.
Anyway, I've been wondering if my current art accomplishments will be a good enough EC or hook for those highly selective colleges? Also do colleges like Yale and Columbia care more about winning in art competitions or service/school involvement that shows your passion? Because I really am passionate about art, I just don't know how to show it :(. I tried joining NAHS at my school but I don't have enough credits and they don't do anything serious, mostly making cards for soldiers and fixing murals around school. I've tried starting a casual arts club with some friends but couldn't find a sponsor anywhere...</p>

<p>I entered the Scholastic competition and received a Gold Key for a painting and am also published in a student art book but is that enough?</p>

<p>Do the admins care if you have accomplishments in your resume, or is having exceptional talent shown in your portfolio fine?</p>
