1 & 2 are really awesome. I love the low angle you got on both of them. The cropping on number 1 was done nice as well. 3 isn't doing much for me. Very washed out with the white subject that isn't all that interesting. But who's do say what is interesting, right? That's just not interesting to me. Still very nice sharpness. 1 + 2 are really cool and not something you see everyday, so I found them unique. And yes, the watermark might be a little too much too.
Nice job.
