Well you asked for honesty.

1# The picture is not high quality and therefore if applied on anything the result will be poor.

2# The photoshop job need to be improved on, you should be able to remove the background of the original snake picture to where it is not obvious that it was done.

3# The concept of the snake with the background chosen while it can be done does not work in this instance, there is no contrast, only dark colors and from a distance it will be hard to tell what it is. If you want it to work chose a light background for a dark snake and vice versa.
