Welcome to the forum.
The first thing I notice about the photo, is that the background is distracting. I don't mind the other guitars being there, but it's probably better if we can't see that the photo was taken in your living room. It just makes it feel like a snap shot, rather than a well thought out photo.
Secondly, the reflection on the guitar. I don't hate the window reflection, but what is that 'shark fin' looking shadow/reflection. That kills the shot for me.
Lastly, the overall composition. I think it would better if you had the guitar at more of an angle. As it is now, it's mostly in the centre and it angles slightly away as it leaves the frame at the top...if the neck were at more of a diagonal direction...I think it would be a better shot. Also, it may be better if the top was in view...but it could probably still look good without it.
