Hi Davina,
There's a difference between how others perceive you and how you present yourself. I am not sure, haven't met you in person, on either. However, I think being genuine and "you" is the best way to present yourself. If others judge you because you are a solo consultant, it speaks more to their biases than to your presentation. Some people are judgmental. They come to the table with preconceived notions, so there is little you can do. 
I agree we should give benefit of the doubt and a grace period. 
Thanks for commenting as always!
