When I first saw him, I got the impression he was screaming in pain or something; that the clouds were overwhelming him and converting him into basically water vapour, like he was being consumed. I didn’t get the feeling of a ‘god’ persé, more like god’s furious handiwork on a poor soul.
Reading your descriptions though, I can see where you’re trying to take the image. Presumably, you’re looking for someone who’s content and elated, hence the hand positions and the ‘excited’ face? I don’t know, I think if it were me I’d take some cloud away from his head because I’m drawn naturally to his eyes and the back of his head is spewing out cloud for some (drastic) reason. If you want him elated, I do definitely believe you should work more on his mouth. Right now it’s basically a gaping hole on his face and doesn’t really convey any emotion (other than, at first instinct, pain.)
All in all, I do like the image and it did make me stop and think which is good for a piece of art like this. I do think what you want the image to represent and what third parties see (particularly yours truly) is a bit mistranslated though and the balancing of the emotion a bit off.
