Although I do have to say there is something appealing about the current planting angle. It lends itself to a windswept style. I think carving the right side of the trunk could help break up the straightness of it.
Or embrace the straightness, change the planting angle to be completely straight up, Shari the entire right side. I actually think that could be the coolest design now that I think of it. Kind of reminiscent of Michael Hagedorn’s foemina juniper:
There’s something so incredibly striking about how straight and symmetrical the main trunk is, while the foliage all originates on one side of the trunk creating extreme asymmetry. I feel like your larch could really shine if you go this route and get real shafty. #getshafty.
