This picture is just stunning. I really like how one of the lightning bolts looks like it's coming from the violinist's bow. Very nicely done. The only problem is the violin, but it seems like everyone else has mentioned it already.
This is beautiful. I love how it appears the violinist is making the thunder.
However, my only criticism is that violin! I played violin for two years and that violin is a little small for your model. His arm would lose circulation after a while and that's not a good thing for a violinist!
Okay, and the bow is never, ever held parallel to the fifth string when playing. It'll hit the instrument and disrupt the flow of music. It'll fray the bow hairs after a while too.
