These are the 3 techniques I didn't put in title: Centered Composition, Leading Lines and Long Exposure
For a DNMC entry, I think score 5.2 is good enough.

So you didn't use the three techniques in the title but I'm not counting off for that. Long exposure, centered composition and low light - that would be my guess.
Love this photo. You're probably getting slammed because you didn't follow the challenge rules. I don't vote on DNMCs, but I would have given this an 8.
oh no! you forgot your techniques :( i'm going to guess: centered composition, leading lines and long exposure? i'm not going to kill it for not having the techniques in the title but feel like a sharper focus on this would have made it more dynamic. 5
