the placement is indeed a little low, but if you look at the amount of lobe you have you will easily reach 0g without any problems , and about it being centered, well your ear will be stretched so i don't think you'll have to worry about that, as you don't really have a center anymore then lol
I don't think you'll have any issues reaching 0G at all. It's a tiny bit low but not that bad. I wouldn't worry unless you were planning on going to 1"+ or something. And even then it'd be entirely possible.
I'm Lindsay.
I have 1/2" lobes and 11 piercings: left helix x2, both conches, both nostrils, septum, navel, and VCH. My lobes are small but I know a lot about stretching and how to do it safely, so message me if you have any questions!
