The stock is way too blurred/smudged for my liking. If I didn't know it was Master Form Sora, I might have had a difficult time figuring out what any of it is, minus the face because that's fairly clear. There's also way too much yellow, you need to add more color to it, because the lack of a variety makes it kinda boring to look at. The background itself is pretty decent, but like I just said, needs more color. Try looking up more tutorials, you're on your way.
I really like the colors in this. However, it's waaaaay too blurred. it would look pretty nice without it being almost completely blurred.
The blur takes away from the whole tag, and sora needs to "blend" in along with the tag itself. I don't like it. Just keep practicing.
