I'm still working on it Alex! In the cold light of day I think I could have emphasised the coma brightness a touch in respect to the tail because it was clearly brighter. I agree about comets - the big difficulty is representing comae and tails that trail off to nothing, sometimes excruciatingly! I've been experimenting with grey paper (light) and doing the comet with a soft grey pencil, smudged. That way there's not so much of a difference between the comet and the backing. Then scan and invert the image in Photoshop. With this one the stars that I'd done with a fine-tipped felt pen were too contrasty and I cheated by applying a light-grey wash over the entire drawing. Next time I'll do it all in pencil. Live and learn hey?

Cheers -
