Well, I got there in the end, and have a reasonable representation with my curved lines and such. Shark has produced a quite magnificent layout incorporating so many elements. My only query is that I seem to have one extraneous letter in my set of matching connected letters, an extra vowel in the lower half, unless that is accounted for with the "all but one" bit of the instruction.
I managed to solve this in strict order; all the clues, then all the four phrase representations, then the bottom line (which up till then I was convinced contained a horse), then the surprisingly complete artwork.
Has anyone else noted that the four representations are themselves in strict order?
