Yes, your detail is good in this one, especially that first frame. I think you need to add just a touch of shading and sketching to your backgrounds and the disembodied heads need some bodies but other than that it's quite well drawn. What's the guy holding in the bottom left image? It's a little hard to see. And the one to the right of that's very nice but add a little more shading?
Remember: the plot is nothing more than footprints left in the snow after your characters have run by on their way to incredible destinations. — Ray Bradbury
