Is this flexible drain trap configuration acceptable?
No. That is an absolute mess waiting to happen.

Go to the hardware store, buy a longer tailpipe so you can lower the trap. Aim the pipe off of the trap for the drain you have that is lower than it should be.

You can buy a proper trap that has nut fittings so you can remove it to clean hair, and jewelry out.  You may have to cut a small hole in the vanity floor / drawer top to make clearance for the trap. Do not try fudging it with that S trap mess.
