You can select the crop tool, rotate it until the branch is diagonal across the picture (bottom at right corner and top at left corner), select the wand tool and blur the two leaves that is taking away the attention from the face of the lizard.
This arrangement should roughly conform to the "y" composition - the perfect rectangle concept
Try this and see if you think its a better picture.
I don't think the leaves are distracting. But by cropping it in different ways can yield different effects. It really depends on what the photographer is trying to achieve.
For example, if you crop more from the right side, the lizard will appear more on the right side. As he is facing the right edge, and there is more negative space on the left, the lizard will look a bit 'trapped'.
If you crop more from the left, the lizard (being placed more on the left side) will appear to be staring into more space on the right. That make the lizard appear more forward looking.
A lot of portraits put the subject such that they stare into space because it appears more positive.
There is no right or wrong.... just what you think is nice.
