Twitter headers can be tricky... Your logo makes sense as the profile pic, but what goes in the header? What did you do?
I put a screenshot of our website in the header, the part that is important and shows our services. People instandly see wat we are doing, not sure if this is a good choice though https://twitter.com/sickparvismagna
Site screenshots seem to make sense! Know some also go an ad/logo route, varied approaches. Thanks for sharing your example!
