Very well laid out. I like the borders you used on the pages and the map illustrations were all useful.
I like the straight-forward way you introduced the adventure and presented hooks to get things started.
It took me quite a while to figure out the numbers on the map, I think part of that was having numbered tables directly above the maps - it might be helpful to place a numbered list of the locations directly above the map and to increase the prominence of the location numbers in the top-right of their respective pages.
I like how you presented the characters in a table, it might be interesting for a GM to roll on it to switch things up with the names and personalities.
All of the Jungle Herbs and Magical Items and Treasures were interesting and you did a good job keeping the locations varied. The Amethyst Slime stood out as a really useful monster, great to throw at a spell caster heavy party.
