Man. Hoooo boy. I saved both. The lineart is clean and I love how you used bold lines for the ears!
Seeing the sketch and lineart side by side shows how much you worked on this. I like the curve of the tails
They are not all the same size and that is very nice to look at. Also, the nose lines. I love how the movement lines are visible yet lighter in tone. The nostril itself has a flare line and I think the feather shape is good! The uneven scrunchyness the muzzle is in right here, it creates feels just by looking at that. It just looks like the entire nose is ticklish and quivering, not just the nostril
That question...is a good one. I swear I've seen vulpix sneezing before online. I asked for vulpix sneezing on DA but it never happened
I did have someone draw Vulpix causing a sneeze to another pokemon XD but not vulpix itself.
