For a signature that's going to be used on forums, it's kind of really huge. Most forums restrict the size of signatures; at cB the maximum dimensions are 640px by 300px (
community guidelines).
I like the idea of it as well. I think you could have erased the text more..... artistically? Like maybe faded it in the places you wanted it erased, so that there's more of a flow. Also, the guitar is hard to make out; I thought it was filtering at first.
