AIGHT! I'm here with a (very) rough outline of what I mean.
What I did here differently from yours is I put a bit more focus on the tentacles and ssubmersion, with the waves serving as a visual guide towards the text and tentacles under the water. I was a bit lost for what to do with the second line (probably should have just expanded the canvas) but hopefully this gives you some more ideas.
This isn't the GREATEST example of composition (it's something I myself am still figuring out, and it can be simultaneously highly specific and incredibly vague), with how unbalanced it is, but there's a few things I adhere to. Rule of thirds, sight rails (not sure the proper term, it's what I call it), and the use of contrast to pull on the eye.
For the former, rule of thirds is a thing I learned in photography, and is better explained here:
https://en.wikipedia.org/wiki/Rule_of_thirdsThe second is something you can see on the tentacles here. I specifically bent the two biggest ones to lead into each other, drawing the eye down from the one on the bottom left into the tall one on the right, up to the spire, then over to the text (kinda flubbed that last bit, unfortunately.)
I also gave them a specific shade of purple to offset from the blues of the ocean shadows, to further draw the eye. There's other visual effects I did too, like the lighting along the "leading edge" of the water surface to give the impression of a half-submerged camera and some mild 3d space to the water surface, but the primary thing I want to focus on are those things.
I do stress again though, I was lazy with this. The use of white for the light muddied up the readability of the text, which also should have been done in a better color to further contrast against the water riding down off the title and pull the eye towards it. A reddish browny-earthy hue might have worked for that, but alas. I also was INCREDIBLY lazy on the storm clouds, and initially planned to put in rain too, but alas.
