I can see your style is starting to become more defined as it has been refined. More details are being added, but characters and objects still retain the same general curvature (in lines I mean, not body shape) or texture (for example, the hair and shirt look like they are made of the same material; elsewhere the lighting and shading is too dominant to notice their similarity).
My biggest complaint here would be the lack of detail in the water. You never find a body of water THAT calm in real life. Of course, since this was practice, I imagine you intentionally skipped adding detail there.
You're doing good. Keep it up. Which reminds me: Are you still using a mouse as opposed to a tablet?
