The second one feels like the best for its focal point. The shallow depth of field with a lens like this makes it hard to get a bug as big as the bee. I typically shoot them with a 100-400mm lens farther back to get a wider DoF. What f/stop were you using? You need to be almost as far down as your lens will let you go for a shot like this.
There is an issue with Uploading Photos (attachjments). I am not sure what the problem is, and I am looking into it. You can still try to Create your Threads and Upload your Photos, but it is hanging up during the Upload.
