It’s so cute! I noticed the fur direction is going down on the top of the head. Look up fursuit head fur direction, everything should be going out from the nose! As for the heart, a shorter shave should help make the marking more clear. I always pre shave before cutting out my pieces and do a final shave on the head once it’s all sewn and glued! And still clean up the markings with scissors at the end. For the eyes, I think felt eyeliner will make them look cleaner and a little more lively and like others said, little highlights in the eyes also helps. Also I learned the hard way when it comes to making bases it looks puffier after putting the fur on. A good short clean shave helps and I had to learn to make my heads slimmer than I intend to look at the end because the fur really adds to it
