I would have two comments:
First, the wavy blobs leaving Alice are maybe conveying the wrong impression. To me, they "look" worse than the darkcoin case: it feels like handwaving - literally. I would suggest making all but one of those blobs come from another direction entirely - not from Alice, to represent the inclusion of unrelated outputs in the ring signature. Then I guess you can have the wavy thing. Or maybe move them to be superimposed, then out again, with all but one disintegrating, to represent the fact than all but one are not in fact spendable by Alice on this transaction.
Second, the square blocks hiding Alice's and Bob's balances at the bottom aren't particularly visible, and you might consider a way to attract some attention to them in some way - maybe with a color change ?
That said, it is well done
