Inspired by some concept art for some of my favorite games in recent times (notably one artist's work on the Spyro Reignited Trilogy.) I wanted to make it look somewhat "3D", and I also added blue light which I saw in some of the art I referenced. Otherwise this is all original. I spent a while but it is not the best (specifically the guitar, I could do better, the headstock and neck are not very detailed or good)
But overall I am happy with this, I do not know if I'll be able to sit and digitally paint for hours any time soon in the future... usually I only find time for this once a year...
