If you shape them like a pine, all you are doing is making a copy of the common neophyte's assumption of what a bonsai is.
Something to always be cognizant of...said another way, make your bonsai look like trees, don't make your trees look like bonsai.
On pointed apices and branch angles, here's my take...this is a very young tree; it's only been in a bonsai pot for 5 years...the green trunk betrays the illusion of age. But, I think it's developed to a point now, where many of the major flaws have been addressed and it will have a chance to age gracefully in a bonsai pot; whether or not the big left branch is a part of the "final" design (probably it won't be, but maybe it will stay and become the thing about this tree that keeps it from "looking like a bonsai"). Old branches point down, apices round out over time, and if you start with a good foundation, it will grow into a great tree.
I think 5 more years in a bonsai pot will bring a more refined nebari, bark, and ramification. I'm sure it will end up wider than it is tall. It's almost even now.
I found a couple more photos of the tree in leaf. The first was last spring. I LOVE the red leaves. The second was at our club's show this summer before it was partially defoliated. You can see how the crown is rounding out a little each year.
