What is the purpose?
Is this a user axe, or a hang on the wall and look cool, axe.
If it's a user, it's a horrible design from a usability perspective.
The scales are going to chew up your hands, the protruding tang is going to chew up your hands, and the center of mass will be shifted from the head down the handle a bit.
Is it a wood axe or a battle axe?
For a wood axe, other are right in that that sharp beard will probably break off in heavy use. If it's for cutting meat (battle axe) the beard won't be a problem, and will aid in hooking bones, limbs, weapons, etc.
Not sure the spike will be all that great. Maybe try something like an upside down American tanto. Think of a tanto shaped blade on the poll, with the spine toward the handle, and the angle and sharp end pointed up. By all means, go ahead and radius into the spike from below, although I'd make it a tighter radius to better enable choking up.
Aesthetically, I like the straight top, but I'd make the furthest point forward of the edge be the point where the top of the bit comes into the edge -- like a Viking great axe.
For the haft on a user, make it a continuous straight haft or curved, but get rid of the points, especially where the palms of the hands are going to be.
For the sake of balance, if you want to have metal the whole way down, at least have the tang flush with the micarta, better would be to use a hidden tang, bolt the micarta to it. This will mean less metal, shifting the center of mass more towards the head.
If this is more of a hang on the wall and look cool thing, then add all the points and scallops you want.
