got enough emoticons now

I had really few maybe 2-3 emoticons before. but, after I posted this I'd like to collect some decent emoticons. some tips please?
I got enough emoticons I guess. You can see the attached image below. some of them I just bought it through the steam market. and, some of them I traded things for them on trading group. spent all day doing that and now I want more. thanks for letting me know how to collect them. <3
