Hmm.. I'd personally (not sure about anyone else) like to see:

(I'm just listing things I can think of, I won't take any offence if you don't do any!)

• Open bait tubs with different contents inside? (Like worms, sweetcorn, pellets, maggots etc)
• A small table which you would have at the side of you whilst fishing with maybe different contents on? (Such as scissors, a spool / reel of line etc)
• A rod bag / holder (like a dark greenish colour)
• Bags of bait (such as bags of pellets, groundbait etc (for like a store or something?))
• Trophy fish? (Like you would a deer head or something on a wall)
• A fish cutting / slicing / filleting table
• A fishing bag? Like something similar to the bait boxes, but with more of a dark greenish colour and a sports bag type look?
• An fishing umbrella of sorts
• Maybe like a unit / shelf on a wall with different floats / bobbers and whatnot in 
• One which would be awesome to see would be like a fishing wheelbarrow or trolley (I can supply pictures / references if needed to help if you choose to do it)

As I said, I was just brainstorming these ideas and I won't take any offence if you don't decide to do some or any!
