What type tree for this style pot?

My problem is trying find the right tree for the pot.

I have three small  (4x4")un-glazed tan pots with fine black line drawings (style below), they may even be transfer-wear, not sure to go deciduous or evergreen. I considered small junipers...thoughts?

The pot will compete with the tree as there is a lot going on visually.

The species in not so important. What you need is a tree that has a really simple structure. Complex curves, deadwood etc will be missed with that pot. A basic broom style chinese elm would be my starting point.

Thanks Brendan, that's a great starting point, I'll try it.
