I hate to be the only one with criticism :/, but I do believe that it looks good, however, for Teemo's right foot (the left foot on the canvas), I believe should have been able to see a little bit of his heel, and some of the detail underneath the boots, like some dark shadow or a slight highlight. Also, I can't quite tell where the source of light is, unless the entire white background is the lighting, because the ear to the left is lighter than the one on the right, however, there's hard lights on both sides of the gloves. I guess the huge black circle underneath him suggests that it's coming from straight above? Also, I think you should've added more shadow/highlight to suggest his snout, as the nose looks flat on his face. I'd suggest just practice more with proportion and lighting, as they're the hardest parts to truly figure out when you start digital painting. I myself am still trying to learn lighting, and even professional digital painters have difficulty. I have some great links you should check out for inspiration/ideas/help: "http://www.ctrlpaint.com/library/" and "https://www.youtube.com/channel/UCkuerBkKrdh-eYzTENy4PXw"
Both of those I use personally, and find very useful. Don't take my criticism the wrong way or anything, but I really just want to help you. I'm still learning digital painting myself, but practice is the best way to get better!
