Just a suggestion, but could you add something in the top of the dome to which soemone could attach a tentacle or something from which to suspend the character in the liquid. What I did in the cryotube I am using now is to place a metallic tentacle from the top of the tube going into the back of the characters head, like in The Matrix. It looks a bit more as though the cryotube is actually doing something if you can connect it to the figure in some way, instead of having the figure just floating in a tank of liquid. Also, I like putting a light either above or below the model in a cryotube, but it looks a bit odd if there is a light shining from nowhere, so some type of thing that looks like a light either above or below the character adds some nice possibilities. The tube looks great and if I can get hold of it I might just replace the tube I am using now. (PS. This doesn't bug me, but how do you get the character into your tank. Maybe a hatch on the top will add a bit of realism.)
