I have made a PSD of the Motorola Moto G for everyone to use.
You can use it and present your Screenshots or ROMs, it just looks really nice when you do it this way.
Here is what it looks like and some examples
I like it more then the normal Moto G wallpaper.
here i did a new one based on the latest moto x aprils fools bootanimation
If anyone has them please share, once I find them somewhere I will share them too ;)
