Thank you so much for your replies, it was very helpful
plant_drew, the trunk is actually very hard so I do not think that it can be wired to get the desired shape. I do want it to remain in its current size, I will be putting it in a bonsai pot soon. The portions where the pruning was done has some brown leaves now, I am just waiting for them to fall off and then I will transplant it to a bonsai pot. At present, I have kept it in bright indirect sunlight as I guess the strong sunlight will further stress the plant. I will move it under sunlight maybe after a week or two. Let me know if it makes sense.
imafan26, I have purposely not shaped it like a pyramid as I do not want it to look like a christmas tree. May be I will wire the tree to make it a formal upright style. As this is my first try, there is still a lot to learn. Thank you so much
