design concept Design concepts for t-shirts

[designbyiq]

Hi, I`m a t-shirt designer and I offer 2 initial design concepts in my package. Design concepts are alternative directions showing different paths to same design. First I show buyer the two initial concepts for the design and then ask which one they like. And then only deliver printable files for that one particular design concept. Is it right to share only one design for printing? Should I deliver both designs? Or should ask for extras if buyer want to have both design concepts? I`m really confused about this.

Thank you!
