Directional layers

I was trying to convey the dynamic layering within the transport

system, a structure which supports over 10 million people each rush

hour

like the idea for the composition ... think youve got it well here... but if youre like me youll be doing this over and over ... you want more cars then you want more people ... then you want more cars with people lol

Yes, I like the idea you've started with a clear idea that you wish to communicate. I think this is a good, but not a perfect realisation of that idea. In pictures which rely on structural or architectural detail to make their point, I prefer it be sharp I guess, which would mean a tripod and preferably a larger camera. Then the passengers would blur, but that would make your point equally well, would it not?

Very dark & nothing interesting in particular, the lines should lead your eye to the main topic of the photo, or make a nice pattern by themselves, something I find missing in this shot
