I reckon the only way to improve the design is by waiting at this point, there's not much there!
You maybe coulda left more to wire, since it's good practice.
Some parts seem to be wired and unbent. A bad practice good for practice.
It's important to plan a wee better so your wire supports the outside of bends, looks like you jump from tight to loose wire angles without much necessity.
This is a worrisome point, where it looks to not only go right round, but maybe back on itself. Places like this can cinch life out.

Truth....I don't think you should have worked them or pruned them. Too early!
Don't be afraid to practice on branches snatched from trees outside!
