nice. Only thing I would suggest is adding some fake plants to 'green' it up a little =) Of course that does add to the cleaning though..haha
Other than that, i wouldn't be too worried about the soaking as long as your sure there are no mites and your temps aren't getting too high where she is soaking to cool off. Once my spider shed after soaking before he even went into blue, he stopped soaking. Just keep an eye on her and make sure everything is fine. She will do what she wants =)
