FIrst, that is a nice piece of nursery stock. I see several options in there. Definitely could be a nice tree in the future.
The question was "how to proceed".
It is your tree, you, and nobody else, needs to decide what you want.
First get a piece of paper, and a No 2 pencil, and an eraser. Check that, get a whole ream of paper.
First draw the trunk and the major branches. Don't bother drawing the needles. Just the trunk line, and the branches that ARE ACTUALLY THERE. You would be surprised how often people are asked to draw a tree, and they edit in or leave out branches so that the end product is nothing like the real tree in front of them.
Now take the eraser, and erase branches in an effort to make it look like a tree.
Repeat, each time you repeat, remove different branches. Rotate the tree as you try other views.
I'm not trying to be a jerk, if you take the time for this exercise, you will find that after the 3rd or 4th drawing you will probably see a design you like that is possible with the actual tree in front of you.
If you are good with photo editor programs, you can do this on a laptop or tablet without using paper.
