Welcome to the site!
I'm not sure what it is, except that it isn't a Brazillian rain tree (which has small compound leaves). Is that a small yellow flower that I can't quite see?
As far as feedback on your wiring, it is too loose to be able to give you any control over your branches. By too loose I don't mean the opposite of "too tight" I mean, you need to put more wire on the branch, seeking about a 45 degree angle as the wire winds around the branch. Once you have more wire on the branches, you can not only direct how you want the branch to lay out, but you can introduce random movement into the branch ( up and down, side to side) so that the branch looks older and not straight like a sapling. Generally, with old trees in nature, the lower branches tend to droop, while the upper branches tend to be more upright. Think like a tree and look at photos of trees in nature. Make sure your branch styling is consistent for the overall design you are trying to achieve.
