Pretty little concept you have here. I really like how vivid all the colours are without clashing or being too noisy; it's all harmonious. The background looks like the kind on a character bio page, which would make sense for this. There's something about the feet/roots that I don't like. I think they don't look "solid" enough or something. Or maybe they're too smooth (not root-like), even though that wold go against the art style here. I'm not sure.
