Salam Farooq,
You have a good eye for a traditional shape, which is a great start. The only problem is that this tree looks very 2-dimensional. The branches are placed either on the left or the right side of the tree. Nothing is angled backwards, or front.
Since you have wires on the branches, try experimenting by moving a couple branches a little forward and/or backwards to make the tree look more natural.
