Instructions
Create a white circle for your first layer.
Create a smaller circle for the second layer with a black fill. Use the scale-down option to make the circle approximately four times smaller than the first layer.
Create a black curved line and make it open towards the left. Place the bottom of the line so it connects to the smaller black circle on its right side and goes all the way to the top of the white base circle.
Create two more curved black lines and place them on the right edges of the white circle, making the right half of the circle's outline black.
Fill in the remaining white on the right half of the circle with a black thin oval.
Create a circle the same size as the small black one with a white fill. Place it in the middle of the larger white circle at the top, allowing it to overlap the black right half slightly.
Use another layer, using the alien symbol, and rotate it diagonally to make the alien face the lower-left corner. Place his eyes on the small white portion remaining on the right side of the symbol.
Finish the symbol with a very small black circle. Place it in the center of the small white circle you placed in the upper-middle portion of your emblem. Place a white circle of the same size at the bottom of the emblem.
