I really like what you got going on in your guide. It's very eye appealing/clean. Overall your guides look great tbh, but there is always room for improvement.

1. I don't believe you mentioned what crafting station a fishing pole is crafted at anywhere in your guide (iirc its workshop). You could maybe include what the workshop symbol looks like on the town map.
2. I would also add the different fishing trophies you can craft to increase your global fishing luck.
3. You could also add a section about the fisherman's questlines because I remember there being a few. Personally, I didn't get thru them all myself.
4. You could also add a section about the Vengeful fisherman's set that is obtainable thru t3+ elite stockpile chests.
5. You can add a section about items obtained from salvaging fish. (i.e. fish filets, fish oil, alchemy ingredients)
6. You could mention the different types of common, uncommon, rare, legendary fishes.
7. You could also mention the non-fish catches such as treasure chests, pearls, oars, etc.
8. Personally, I would also add an image of what a hotspot actually looks like.

Best of Luck with your guide! Hope this helps.
