Just watched the video Poppa, really nice!
I think the “blue smoke” is just right!
As for the eyes, I think I can go either way really. I think it is done well, it is more a question of is it needed? I think it’s neat, but is it too much of a hint? I think the smoke is fine as it is and doesn’t really hint at much since it is so quick … which is a great thing.
Of course you can keep working on it, but I think I am leaning towards keep the smoke but not the eyes. Maybe. I’ll keep watching it and pondering about it more and more.
