given the op’s grades as stated , if he were to choose an “art school” his grades wouldn’t hold him back . What is more important is the quality of the portfolio . Also taken into consideration is dedication to art (experience and references).
Our D was accepted to all the top schools (other than Cooper which is a whole other story) with similar grades in fact slightly lower. That includes Pratt among others. If the portfolio is very strong it carriers the most weight in all situations.
