Thanks for the advice, DB.
Just went and checked and the situation has changed slightly. The mountain range isn't as high as it was, good. There are a couple of splits opening up, bad. Two small splits/cracks around burls, probably won't notice when sanded and finished.
From the last pic, the small middle ridge, closest to camera, has split along its length, about 1cm long and .5mm wide. Looks like the veneer wasn't dry enough. If that is the case and it keeps shrinking/drying out, it may need to come off, will wait and see.
Want to use stronger language than Bugga!
