SAT and ACT...Are My Scores Good Enough?

Okay so I scored a 1790 on my SAT but I'm not sure if I should take it again to try to get a better grade. I also scored a 28 on the ACT, without the writing portion. I'm not sure if taking it without the writing was the best thing to do, but that's what my counselor recommended. I know that the requirements are different for each field of study; I plan on going into visual and performing arts in college. I have no desire to go to an Ivy League school, so that's out. Are the scores good enough for anything beneath that?
