i just got a 34 on my act, which is excellent for me since i want to go to northwestern... and i took the writing because they require it.... but.. i got a 7 on the writing... will this hurt me?

here are all of my act scores:

June 07 -- composite - 30, writing - 8
October 07 -- composite - 30, writing - 8
February 08 -- composite - 31, writing - 8
April 08 -- composite - 34, writing - 7

sat:

720 - math
650 - reading
700 - writing

2070 overall
(sat has always been harder for me than act for some reason)

8 on the writing (both times i took it.. these are my best scores bet/n the two tests also b/c my college counselor told me that all colleges [except the ivies] take the best of each section on the sat)

anyway, i'm taking the sat in june to see if i can get about a 2150 - 2200 +, so i'll see if that will give me a better writing

but, will the 7 hurt me anyway.. i mean my original english score was a 35, and the new combined english/writing score is a 31... so if they plug in the 31 to the mix instead of the 35 for english (if they do that.. i have no idea), then i stil have a 33 overall, despite the average writing score.. i'm just worried that it'll hurt me
