How much is String art worth?

Question:

How much is String art worth?

My wife makes this paintings from strings on a canvas. Here's a link to show what the style looks like, but it's not her painting (this is how she makes it) http://www.arttechnology.com/worldwithou...

But her painting has a girl sitting down in a forest with trees around her and some sort of musical instrument in her hand. She looks sad too. All the shadows in her painting are perfect as well. So what's the worth maybe on average?
