I think that having a much more defined shap on the other side of the glass would help this image. Something familiar that would be recognizable, but while using the glass as a new method of portraying the subject.
Interesting. The lighter area on the lower right is a little distracting from the focal point of the rider. Perhaps cropping out part of the right side would make this stronger.
Sorry but not my cup of tea, I am not and probably never will be a fan of abstract work and this is no exception, this shot makes no sense to me. Just thought I at least owed you an explanation why I voted it a 3, there is simply nothing about this photo that I like.
