The view is mostly of the guitar strings and frets. We see the fretboard / fingerboard running down the middle of the wallpaper and then we see the guitar body up top.
The focus is mainly on the fretboard so the rest of the guitar like the body of the guitar is not in focus so it's very hard to make out if this is an electric or acoustic guitar. I'm gonna take a guess from the size of the body of the guitar that this is an acoustic guitar. But I could be wrong about that. But I do know that this is an Gibson guitar.
I'm gonna point out that the inlays on the fretboard looks very nice. I like that about this guitar wallpaper. And also the warm feeling that this wallpaper have.
Well this guitar wallpaper is of the size 1215x799 so will fit well for people running widescreen compuuter monitors also.
