How to do the pictures?Choose a neutral background. The same for the floor and the wall. Best is only to wear a short.
I suggest white for the background and black for the short. If you want to wear a T-shirt, take a red one.
Using those colors, I can mix poses from different people in the logo.
And be inventive. The more flexibility is used to do a letter the more chance there will be to make it into the logo.
