Does my open bite look like its coming back? (photo)

I got my braces off a few months ago, and have worn my retianers religiously. I have a pair of essix retainers and one set of regular ones with a tongue crib in it. One tooth shifted a few degrees and now im wearing invisalign and im afraid that my tongue thrust is pushing my teeth in my sleep. Does it look bad? If so, what can I do?
