Not bad. Decent taper but could use some movement. Looks like some OK potential for root flare development in the future.
Really liking the looks of the area you collected this from.
I would be tempted to chop somewhere in this range between the blue lines where it starts to lose interest. To me this looks like more of a graceful flat top later on rather than pyramidal.
Seal the edges of your chop, clean the roots well and remove anything that doesn't belong, put it in a tub with some 50/50 mix, and watch it take off!
