So is what I have good or is it improper and I should try to learn barring with my finger lower?

If you can play those chord clean, clearly & efficiently, then it's perfectly fine.

Every individual set of hands is unique. Everyone has to find their own best finger placement depending on the microplacement of the topology of their fingers.

Your index finger looks fine. Your other fingers look good, last knuckle & tip straight down into the neck. Your wrist looks to be in a comfortable natural position.

And it also depends on the guitar. In this case, your Fenders has a pretty narrow neck. On some of my narrower Fender necks I have a similar finger placement. Check out my tutorials on barre chords for more detailed advice.
