Avg. softs, good PS, with work experience

Before getting this score, I was planning on apply basically Columbia - WUSTL plus SMU, now debating on riding a cycle out and seeing where things fall or retaking December. Is retake the right option here, even with the multiple scores I would have and the fact that I won't be complete until January then?

also, i have never been super detailed or focused in my study and i went -9 in LR and -1 in RC and LG in October
