That's very sweet! Love the stork, too!
With clouds is such a tricky story. You have to understand that they are not cotton balls! I'll try to explain that a bit more in the tutorial I've got planned, but it'll be tough. They are diffuse refraction and reflection combined. In some way they eat the light and you see their belly glow, so to say, but if a wispy part of their "skin" floats before the "belly", it would be darker, for example, not because it doesn't catch the light, but because it's volume is not dense enough to diffuse the light that goes onto them, yet it refracts the light that was meant to go through them from the bright cloud behind the wispy piece. It's really, really hard to think about it, but I'll try to find a way to make it easier.
For me it's still tough to make really good clouds without having to focus. There are neat little tricks to make cute Bob Ross like clouds (or Kevin Hill for that matter). They can be just sufficient. But if you want to go nuts...uh... it'll take great discipline and focus.
