Aww, i like the cute style. The colors are nice and calming too. The pose is fitting for him, even though it doesn't seem the most logical. The lineless aspect adds to the soothing aspect and feels like it removes linitations. I feel like the background is a bit sickly though, maybe you could have used a different color.
Overall pretty cool pixelart, though it's a bit of a weird pose and the background is not that great. Keep it up!
