I mean 4.5 is not a bad score as far as I know, is it? 5 would've been better but 4.5 is like 78th percentile, which is a respectable score in my opinion. You should not worry about it. On the other hand, considering the GRE's average mathematic level, I would say that 152Q is quite low (or average) ... but I don't know how much the schools you are aiming for emphasize on quantitative. Your verbal is better than average (70%) but not exceptional either.
If you want be safe and not worry about your GRE score then try to aim at least for 161Q, 159V and 4.5-5AWA.
