Hi Mike, nice job on this tree. Don't be too hard on youself. This tree now has the foundations of a good overall initial structuring. As fas as removing the foliage so you can wire, that is true. However, tt is a good idea to leave maybe some young growth if you think you would like to create future branches from it. In this case, when you put more movement in the trunk and branches and with time. the pads will form and fill in nicely. Your structuring here has created a nice future tree and in no way had detered it from becoming a beautiful future bonsai.
I would let the whole thing grow freely for 1 year. Next spring, you can cut back. Also, the small pads will have grown out, so they might need some wiring within the pads themselves. This will create well structured and ramified pads.
