Happy Happy Happy

Quite amusing, except the amusing elements don't really stand out—maybe amp up the contrast on those elements? I think the plants in the pond detract from the amusement [they wouldn't pop up like that after being trapped in the tin IMO] as does the grass on the tin's lid which is not consistent with the notion that the pond is totally artificial. More fundamentally, I'm not sure the fish are the focal point as required by the contest requirements.

lol, creative idea author

I think the can lid might be better off left metallic or with a hint of green reflection, but I love your concept. You could try lowering the opacity and maybe a slight blur.

Pretty funny! (Bubbles could be better).

Love the pink fish and it's expression

lmao ;p

Surrealism is a good approach for this theme. I'm not sure what tale the fish is telling, however. IMO eliminating the distracting wallpaper so the windows and baseboard are just suspended in space would be more surrealistic and would give a lot more attention to your dramatic background photo (which has erroneous lightning reflections in the water but those should not be visible here). I think the fish that is supposed to be the focus would then stand out a lot more. Even if the window pair were centered, I would consider deleting the right one and moving the left one so it's centered on the Rule of Thirds' left vertical line. The table and chair have different perspectives than the floor. The scale of the chair is odd given that it's in front (not way behind) the table. Nothing seems to be casting shadows. [Surrealistic does not mean totally unrealistic.]

I agree with DanLundberg on the wallpaper. The color/pattern of the wallpaper is taking the focus away from the fish. Its completely up to you if you wanna keep it as it is.

This is much better IMO. I like how the cool green/blue/neutral palette of all the background elements makes the warm orange/yellow fish stand out more. I also think the title revision with the new exterior view that's under water creates a more coherent story (or tale, if you will ).

Are those glasses connected with horizontal tube like things?

I would have probably tried to make it look like those glasses were connected, at the moment they still look seperated. There is no way those fish can get from one glass to another. I like the idea however
