A few more smileys to add to the existing set: (http://www.canterlot.com/gallery/image/4665-pony-smileys/)
As before, these are sized for optimal use in IPS forums (like Canterlot here). They're pixel arted, so they look amazing at native resolution only. If you bring them to chat rooms and other forums, they may have scaling forced on them, but most of them still look decent, in my experience.
The same distribution rights apply here as they do to the larger set linked above: Use wherever you like. No need for credit, but shout-outs are appreciated.
Constructive criticism is always welcome.
