A couple of quick tips...

First of all, there is some vignetting to the photo. This means the corners are a little bit darker than the rest of the frame. This implies you are using a light source that isn't intended to be used at that particular focal length. That can be fixed by diffusing the light (read my post in the previous topic).

The next thing that might make this photo a bit better is to get a little bit lower. Usually taking photos from 30° or lower gives a herp photo more "personality".

When shooting herps, it is generally a good practice to make sure the animals eye is in view and in focus. You can't see the eye here and that diminishes the effect of the photo.
Also, the photo would have more personality if the animal was facing the camera a little more. Usually having the animal facing one of the lower corners of the frame helps.
