If you were looking to capture stationary hands on a guitar, only the second one, which is quite dark, even approaches what you were hoping for. The first one looks like an advertisement for the Squier Telecaster. That's fine if that's what you were going for, but it's a fail if you were wanting to capture the hands...
As stated both images are unedited and were just two random examples. The theme of my project is people so provided there is some part of a person it should be fine . i might not even use those 2.
