But let me break it down for you, first you need to make sure it is your own artwork, or if you commission another to make one for you. Which there are a lot of awesome artists out there to do just that.
Come up with an idea, best ways for me to go about this is to think of what people like to use most.
For example, Love, Shy, Hype, Fail, Hey, R.I.P.
For twitch.tv as long as it is your artwork you can come up with emotes that has copyright like Mario, Zelda, sonic etc.
But some streamers find it better to not have any copyright material in the emotes so you can print them as a t-shirt/hoodie and merchandise them.
