1 and 2 aren't too great, nothing really stands out for me..then again I take pictures of nothing all the time..its all subjective anyways. But I personally don't like them, especially the added lens flare. In regards to the lens flare, I don't know if it was your intent to have colored lens flare in a BW picture..i'm not a big fan of BW pictures with selective color, most of them end up looking corny as hell. Also, just noticed, #1 isn't really in focus either. I didn't mean to tear you apart with the first two..
3 is amazing! just the BW conversion wasn't great. Gotee posted an edit that really shows the potential in that picture, I love that one..good job.
Keep shooting..you get better everyday
