I think you are a strong candidate.
Just a couple thoughts - you mention an “arts concentration” - what is that? Do you mean you want to take a lot of art classes? Have you looked at the requirements for these schools? There is not a lot of time for extra art classes. Also, what national awards do you think most 14 year olds have won?? I will answer - almost none! I don’t know to whom you are comparing yourself but kid, you must stop!!
