What we'd like from you...
When creating a design brief, make sure you explain what your requirements are as best you can. Given us designers are highly visual creatures, adding examples of what you like, some doodles you've made, or even color swatches that appeal to you can be a great way to communicate your vision effectively.
Don't just focus on what your design should look like, consider and explain other factors - Who are you trying to appeal to? What are you trying to say? Who are you and what is important to you or your company?
Giving this type of information can really help us create something that will be both meaningful and effective.
