My First Signature [C&C]

It's not bad, but I wouldn't really call this a sig? Well it's just a render with the line going through her. It is pretty good, but more could be added.
Even though it's transparent, it still has the rectangle "look" to it (because on the right you can see it's cut out, and on the bottom, etc).
Hmmm 5/10?

 

I think the green is a big too bright on her, makes it look more like a snake.

I also fail to see how this is a signature, it has no depth or meaning, it's a un edited character + a green wave.

However, i do like the wave effect in general, i'd recommend that you practise a bit more before you post another one.

 

The transparency ruins it, the pentooling color(lime ass green) doesn't match the render, it's got a box-look(like draucia said) even with the transparency(which is why it ruins it), the text doesn't even need to be there, and it's bland/boring. Read some tutorials and make a proper signature.
