In my opinion, your bed looks pretty level, based on the brim. But the entire bed is a smidge too low. Unless that brim is more than one layer.
How is your ambient temp? Is there a heating vent nearby?
Another thing is that design, tapering down to a fine edge like that will tend to pull up the corners because as the filament cools, it shrinks a bit. So each subsequent layer is printed in place, shrinks a tad, and pulls inward on the edges. That kind of design is actually something I use to test my bed levelness, shrinkage, and temps, because it is ideal for getting these things set because the design tries to pull up the corners.
That's where an enclosed printer comes into play by keeping the inside of the printer nice and toasty, and cinsistent, preventing as much shrinkage and bed delsmination.
Solution, raise your bed slightly on each corner and try again. My first layers, I generally try for the filament to look a bit translucent. Make sure your ambient temp is pretty warm if possible, and doesn't vary every time your furnace/AC kicks on because of a vent nearby.
Having your bed temp too high can actually cause prints to warp more than running a lower bed temp. I run at 62°, and that works fine for me, but you need to find where yours prints best at. If I print with my bed turned off, I actually have less warpage than with prints with the bed turned on sometimes. My CR10 S7 Mini taught me that, as it doesn't even have a bed heater, and when the prints stick, it prints beautiful parts
