This is a wicked awesome improvement!
Let me say that the lighting is OUTSTANDING!
From the sands, to the sky, to pretty much everything else, it's really well done.
The shadows are very impressive, only flaw is [and not very noticeable] some of the shadows on the plant directly under your signature are curved weird i'd say. The bottom three are good, but the top two look wacky to me.
I understand how you were trying to bend the shadows in order to fit the spherical shape of the plant, and it probably makes me a hypocrite by pointing this out, [because i'm not a great artist] but that's just what I see.
The "wind" effect that you pulled off is bold, well executed, and adds a great thoughtful feeling to the entire picture. You colored the wind folds in its clothes well.
I freakin love the spool character!
The way he's holding the needle, he looks like a knight.
Character design is undoubtably one of your strong points.
There are some parts that I don't understand or can't recognize.
I don't know what to make of the first plant on the left, or the towering structure, but my first guess for that one was it's a castle.
