I think the concept's sound and that shooting into the light worked just fine here. I really like the first one's idea but I think it needs a more diffused light on his face as it is burned out there. Otherwise it's all there... Perhaps you can fix the bright spot in PP? I hope so.

The bottom one works too IMO. I like the daring composition but feel that it may go a little too far - I'd crop some of the left off. Wonderful sky, and exposure on him (you).
