nice work so far, i think your idea has the basis for a gum tree, yet i feel the way you plan on branching the tree might not seem natural

i am no gum tree expert by no means but from what i have seen in nature gums have a couple of different ways they can branch of.

as you can see in the example above the branching has a flowing nearly abstract design yet looks very natural.

yet this one has a bit more of a rigid sharper bends in the branching.
i think if you can mimic this sort of behaviour of the gum trees where they have sub trunks or main branches that go up then go out with twists and turns whether there smooth and flowing or more rigid and sharper, you will find a more naturalistic tree within the design. thats what i would be aiming for if i was doing a gum tree. i think it would be quite acheivable to get this sort of idea in not to long a time.
one other thing i noticed with the gums is that before the get to there branching the have either heavy sub trunks or branches before they span out to the flowing twisted branching then to the fingers of branching where the foliage is at the outer limits.
just an idea for ya mate

hope it helps.
