Black and Whites from Myongdong

I'm thinking of submitting some photos for the Seoul City Blog photo contest.  Since most photos that I take are for personal use or for my blog I usually shoot in small formats so as not to waste space on my hard drive/ storage space for Blogger. That means I'm on a mission to take some awesome new photos in large formats to submit for the contest. Here's a few of what i came up with on Friday night while walking through Myongdong. Please let me know which photos you like and and which you think are junk. Also, please tell me how I could improve!
