for suggestions on the diagrams themselves:
STEP 24: the instructions says "repeat from step 5", but step 5 says "turn over". that's fairly misleading. I would prefer to see the next step or two shown in the sequences, which is to spin the model, make the next fold, and fold again to center. after that, it's easy to repeat the pattern.
STEP 39/40: you don't instruct to turn the model over, but it's supposed to.
STEP 40: it says to create the two pre-creases, but they already exist from a previous step. i wasn't sure what you were trying to indicate, except to score them again?
STEP 43/44: it's not clear that by "do the same at the other end", i believe you mean that it's necessary to pre-crease the same two lines at the tail end, to form a pair of "linked diamonds". the picture with this instruction shows the fold-through-all-layers on the head end only. you cannot see the second diamond on step 44, but you can clearly see it on step 45.
fun fold!
