Try doing more challenging animations! This is getting to be a recurring style in your pieces. Spice it up! 
If you want to keep the AA, but also keep the transparent background, you could add some white outline to the subject. But, since the latter only works on bigger pieces, I would suggest removing the AA or just putting a white background.
@Jalonso ya, sure I don't even use the default gray :b I'll keep it in mind if I make another piece similar to this.
Looks fine on trans but if you leave trans then the outer grey AA on the antlers shoud be ditched. Not everyone uses the default grey theme.
@BathMaster 2000 I can't animate for the life of me, I also kinda prefer the minamilst animation to pixel pieces. I doubt i'll be making many pieces if any in the future so yeah.
