Yasuo Poster made for LOL contest

My first digital artwork *-* Unfortunately wasn't chosen for being one of the winning pictures for the contest, but I tought I'd upload it nevertheless to ask for construcvtive criticism. I made a huge progress while painting this (and it took also waaaay too long, approx. 20 hours, including watching tutorials and so on) and I want to continue making huge progresses in the future Please let me know what you think of it
