This is excellent. The main emote is fantastic with plenty of detail packed into such a small space. the animation on this little guy is spot on, the tears and the nose rub could be lost given the blue colour, but they aren't and it works very well.
The glomp animation is also a really good rendering of a popular existing emote, not too long in it's appearance and the thought bubble is smooth to appear with a great pop ending. The only thing you *could* add to this would be a little shadow under the main guy, echoing the shadow's under the glomp characters, simply for consistancy. But you would be justified to omit that if you intended this emote to work against any background so this really is a very small issue.
Would've done a critique but apparently cheap-asses are butted out of doing that xD. Regardless, I can speak on it. The overall set-up for what's trying to be told is executed well; nice visually and pretty much clear on the message. I'm guessing, but I'd say little blue is sad that a certain purplely buddy's not around to cheer him up (I was gonna say something a lot more grim before but I figure that'd be out of place). The cloud-dream poof effect's nice too; it's convincing. The only thing I'd want more of is if the emotes were larger, but then again it wouldn't be an emote I guess but it's a good thing there aren't a million things going on in it or else my eyes would get lost xD. Great job buddy.
