I started to post and ask if you really wanted a critique, but since you said you did, here goes:
The blade shape is too pointy and angular - you would have done better for your design to make a cardboard or wooden template and see what it looked and felt like.
The handle will be very uncomfortable to use.
You say it is balanced? Without the handle on it, its not balanced yet.
Some suggestions ( for the next one):
Make the spine a continuous curve from the handle to the blade tip. A big hump with that jimping will be rough on the eyes as well as the hand.
The bird's head butt should be a smooth drop, not a sudden notch. The handle belly should only have a slight curve and end in a smooth rounding at the ricasso. The way it is now will raise blisters.
You have two holes and the thinnest section of the handle in alignment. That could lead to the blade breaking in half during use.
The blade edge should be a smoother curve. The angle in the center and pointed tip will make it usable for nothing but stabbing someone - I hope that is not the reason it was made. The tip as made will be very weak, and probably break off un any normal use.
Look at some of the sketches and templates other new makers are currently posting in Shop Talk, and you will see some more practical and better engineered shapes. Here is a good one:
