<p>Do you intend to become an artist? RISD is near Brown and you can take classes at Brown as a student at RISD. I think the opposite is true also. Either way, for a 4 year liberal art college, you could continue with cast drawing. For an art school I think a portfolio with some diversity is better so in that case I would take up painting but to keep your cast drawing skills sharp as well. Don’t sacrifice your passion to gain a new skill just for a portfolio.</p>
