You seem to have a good eye for bonsai design, something not everyone has. I would like to see you get your hands on some bigger material and see what happens there. Learning bonsai design and acquiring the skills to pull it off with regularity depends on good old fashioned repetition. I cannot see the details of your wiring process but I suspect this to be a really good place to begin a course of study for improvement. There is a rhythm and design to the way you wire, it is almost like a dance within the branches, I looked at your wiring job a bit closer and you do have something to learn about this aspect of the art. If you want to serve your self well I would suggest starting there.
Here is a link that you will find totally valuable: <Craftsy@create.craftsy.com> There is a free set of lessons on wiring. By Colin Lewis; Very good, detailed, practical and make sense.
