I really like that first one. Sharp and nice DOF. Personally, I'd clone out that lens flare.The eye is really cool in the second one, but something about the overall image disagrees with me. Maybe it's cropped too much.
Wow, fantastic! The detail in that eye is incredible, and the whole posture of that first shot was quite a lucky find.
Not sure what's going on above the frogs leg on the glass though... Some kind of orb, probably a flash bounce. Could use a little editing just there...
