Yes, both have far too much headspace for when fermentation slows/stops.
Here's a photo of some of my wines, to get an idea of where you should top up to (this is an photo from a busy racking day!):
You want to top up to the narrowest part of the vessel, near the top, not where it's wide. In a couple of mine, even they are a little lower than they should be but I knew I was racking soon and didn't top up as fully as I should.
