What do you think of my paragraph?

It's an interesting piece although I must admit it is a little confusing. I think you could just put a period after 'scattering animals in her path.' Reason being 'about the trunks of trees' makes me think she's knocking heavy trees down as she goes. Sometimes less is more. The last sentence runs on, so break it up. Plus you said she was turning into a dog so 'scarlet bullet' brings a strange image to mind. It's good - keep working on it.
