You've got yourself a very nice twig as the main trunk and I believe your smaller branches are appear to be flower stalks. An excellent start except the tricky bit is trying to reconcile the smaller flower stalks to your much larger main trunk. The flower stalks have stalks that are a bit to small in girth relative to your main trunk. The other thing about using flower stalks is that they have no tapered effect in their girth. Unlike real branches which are thicker at the base where it joins the main trunk the flower stalks is unfortunately uniform throughout.
You could overcome the effect by placing more flower stalks packed in a more dense arrangement thereby drawing attention away from the smaller branch girth.
Being cheapo and hating the thought of shelling out good money for vegetation have resorted to go to Mother Nature. In the pic below the small trees in the background have trunks were substituted with larger pieces of twigs because being entirely flower stalks the main trunk was too small relative to the 'branches'.
A good source of low shrubs is the dried flower shops. The one in the foreground are smaller dried flower stalks with dried tea leaves for foliage.
