Hi there,
nice looking model! The guitar stand, strings and other metal parts look really good.
But the body texture looks odd. The scale of the texture is too small, and i think the wood grain should be turned 90 degrees. It looks more like a shed wall at the moment. Also guitars tend to have a high gloss clearcoat on.
Dust on the scratchplate looks good!
Nice work!

Good to now, thanks for tips Sami. 
I have to disagree with Sammy, I think the wood texture looks unique, as if it’s handmade. Now if you’re going for a production model guitar, then yeah, maybe it look a little odd, but to me it looks like a custom guitar(I’ve actually seen one similar). I think it looks great.
I agree with @cmomoney, this texture makes your guitar one in a kind. And, to be honest, I saw stranger guitars than this one 
It’s a great render, I just find shadows a little bit too distracting - I know, that playing with light was a matter of this picture also, but to be honest, for the first sight I wasn’t sure what am I looking at
