Oh boy, the sentimental value. I love the painting, and it contains particular meaning because I do play violin, in a heavy metal band. Admittedly, it's an electric, but none the less.
The contrast between the brightly coloured and almost acid-tripping background and the distinctly tonal metal is really well executed. If you were to put a tad more blending into the humanoid's leg, it'd be just perfect.
On that note; about how long did this take you, and was there any particular origin of the idea for the bow to be a serrated sword?
