Character design is decent. I'd recommend modifying Lux so that the skin tone is slightly contrasting more with the jacket, and maybe making his mane a bit less highlighter yellow.

Otherwise, the narrative feels rushed. You have this character that is like the 2nd most powerful god being pushed around by an underling until it's plot-relevant for him to pull rank. He also is super weak and powerless, again, until it's plot-relevant.

If there's a reason the MC is hesitant to call rank, develop this more. This interaction feels like I missed an introduction, so much is happening in this intro that it's a bit overwhelming.
