Looks like the regrowth or later growth is good, but the earlier leaves had that leaf-curling aphid. It should have moved on by now, and there’s not much you can do anyway, apart from TLC. And if you aren’t on a limey soil, a handful of coarse oystershell grit scattered on the soil around. It might like that. People feed it to chickens, you buy it loose from that sort of shop.
It looks a bit dense in the middle, you might want to thin it in late summer, taking out crossing branches and ones growing inwards. Not much, a fifth or so, to avoid a big shock to the tree. You need to know about cutting at the collar, and the safe way of cutting without ripping the bark downwards.
