Quite a different looking Assassin Bug than the ones we get down-under adcolon.
One of those difficult critters that seem to be all legs!! Your approach to crop the legs and zoom closer to the head/eyes I think provides the best impact. Good exposure and detail.
Good move to crop and cut rather than clip any of the legs. This also brings out the details in the head and face much more. I would crop even tighter.
Good sharpness also. Flash looks a little harsh though. I always diffuse for the best effect, even a sheet of paper or facial tissue taped on is better than a bare flash head.
I could be wrong, but I don't see an Assassin at all. This reminds me more of a stick insect and it could well be a very small immature one at that. But like I said, I could well be wrong. Maybe more of a small one of these.............
