I have a few tips!

Bitmoji is an overall good app, but there is always room for improvement! I love how you can use it for Snapchat! Also, I love how it has many options, but their is something missing! Freckles! I think freckles should be added because a lot of people have them! You could have options, like the other details. No freckles, a few freckles, a good amount of freckles, or a lot of freckles. I feel as if this would be a great addition to this app! Also, I have an idea that, in my opinion, would make things much easier. You would take a picture of yourself, and Bitmoji would generate your Bitmoji avatar for you! It would be easier for the users & would reel in a lot more people who would be using the app! Some people dont use it just because of the hassle you have to go through to make an avatar! These would be great attributes, even though this app is already awesome!
