The tree textures look perfect, though I can't help but feel the way the turtle looks is a bit off. Perhaps it's the serpent-like neck he's got where the neck appears a bit thicker on the upper half than it's lower half. And also perhaps because the shell doesn't reach all the way around it's body and only covers his back, it's a bit hard to tell it's a turtle and not say some form of baby Brachiosaurus. But the textures on it's skin are quite nice and fleshy, and the water reflections have just the right reflectivity I think
