Do you think I should make a Logo?

I want to make like a logo? I wanted something like if I make a Twitter, Facebook, or Pinterest this could be the picture. I think it seems very young and not professional but I think it is also cute! 

I don't know, if I had somebody weigh in their thoughts in how they like it or they think I should make another or if I should even make a Twitter, etc.. 

I think I might make a couple and people can choose from them.
