Thank you very much for the feedback! Normally I put a bit more of detail into the eyes, but I was kinda trying to emulate something I saw on other picture. I'm glad you like the mountains, I think I still need a lot of work drawing that kind of stuff, but I'm probably on the right track if people like it(?) Textures is something I would like to experiment more with in the future, definitely! I don't quite get what you're trying to say with "the wind and the smoke effet need be to a bit more in this art." Though.
I use a Mayflash F500. Here's how it looks on the actual stick https://twitter.com/EnmaDarei/status/1350250243414134784
I used the https://focusattack.com/ template, they have templates for a bunch of different models of sticks.
