Your idea is interesting. Non-generic advice would be that you did not spend enough time in your deck quantifying the financial opportunity, addressing the risks of writing legal contracts or as you put it 'setting the standard' and describing the business model. What is the current state of the application, demo, beta? Who is your competition? Basically you stated that you wouldn't have any, this is very unlikely. How are people solving this 'problem' now. If people aren't getting contracts for a photography session etc. now, then who would pay for this? I would like to see a target customer.
Also, you have not included much product validation or market fit research in your deck. My sense of your presentations appear to me like a very tech oriented idea more than a product at this point. Not unusual for early stage, but that image could be changed by including a productization road map in your deck.
TLDR: Focus more on communicating customer validation, monetary size of opportunity and your business model.
Good luck!
