This is a very nice and enjoyable chapter, I prefer that he is focusing on the more relevant strawhats and we are having them being characters, interacting, i finally feel them "alive" and not 2d sided, better to not see Robin at all then see her stay on the ground for all arc like egghead.
I like the Sun God design and I do think they are the holy knight we've seen with Garling or at least a relative/connected character.
Overall I am enjoying it, it's a start of an arc of course I cannot expect big things so it's a "nothing too much happens" but better than wano for example.
Luffy being so adventurous and run away it's normal, remember Roger acting in the same way towards Oden and him running away from a far from prime army Big Mom.
The main issue of these chapters is that as many said after so many time, after entering the final stages and when we need answers Oda should not waste time on brief matters and then rush important stuff like a proper Kaido flashback etc.
