I would like to point out my own OCD thing...that if you actually have a full drop that hasn't smooshed against the glass, the image is inverted as the normals come from the opposite angle. You'll see the entire image is reversed, top to bottom, left to right. That makes edge blending difficult, but it's more accurate. I could tell your normals don't ever invert because the fire is on the same side of the drop as the fire itself.
Good work though, not too many people will notice OR care!
