Nice! Slightly unlucky with the last layer. For OLL maybe you could try this instead: R U R' F' R U R' U' R' F R U' R' F R F'
Is your centre solving strategy any different because the cube is bigger? I was wondering if maybe it is better to start from the middle and expand outwards because it is a bit harder to turn?
EDIT: Maybe even rotating the normal alg would be good? z U' R' U R' U' R U R U F' U' F z'

Well, I prefer starting from the middle, because it's harder to lookahead these middle pieces, so I solve them first, and then I have mostly "normal" center pieces (I mean the ones that are on a 7x7 too). I think this is especially helpful if you are not used to solving cubes bigger than 7x7. And honestly, I have never thought about the turning hardness of the layers
Anyway, on cubes till 7x7, I don't care about the order of the bars, but on bigger cubes, I prefer to solve them in "couple", so for example if I solve the most outer bar, then I solve the other most outer bar, to simplify lookahead.
