All right. Here are a few suggestions.
Try to make it Blocko.
Use the size and proportions of the default Blockland face in order to make it more fitting with the game as well.
Possibly just modify the eyes of the face (default) with the colorful eyes, I forget what it is.
On the ears, you used different thicknesses and colors of lines, and the overall effect was not attractive. If you try again, I would suggest using lines all of the same color and just filling in the center.
Also, to make sure the face is symmetrical, simply select and copy one half of it, delete the other, paste it in its place, and then reverse it, and you have a perfectly symmetrical face.
Other than that, I don't think that I can help you.
