The title fortunately gives the scribbles some shape; otherwise it might be hard to tell what was happening here. The hand shape is rudimentary and messy, and doesn’t seem to be gripping the handle of the hammer (which itself is only suggested by one line). I’m sorry, Artist, but this is going in the lower tier. Try to keep control of your forms, and thanks for contributing!

I liked the ripple effect, here. It really gives the piece a sense of weight and motion.But I do have to agree with GGA that it's tough to immediately make out what's going on. for instance, I can clearly see a thumb, but I can't tell where the other fingers end and where the handle begins.

I think this works well. It's messy, but that's the point, like it's a physical representation of the really loud noise that must have just sounded. I do wish I had seen it before I saw the title, to give a better idea of how clear it is.

And I'm curious why you chose purple for the background. I feel it takes away from the "forge" setting a little bit, and the contrast with the white isn't very friendly.

This picture makes me want to cover my ears, but in a good way.
