So I normally do voice over and I had a buyer, a new one actually, recently order from me. He sent me an example of what he was kind of looking (like in tonality and feel) for but then told me in the messages how he wanted it to be a bit different. This was super helpful for me because I knew exactly the feel and the emotion he was looking for in his voice over and was able to get him exactly what he was needing. So if you’re not sure exactly how to spell out what you need, find an example of what’s at least close to what you’re needing. It may just help the seller be able to have a better idea of what you are looking for in your product!
This is valid advice for plenty of categories.
Note, Buyers: please don’t just go “like this” and leave it with no context. A picture might be worth a thousands words, but keep in mind that people can and will come up with different words than expected.
