3) Duranta
material: good choice, this kind of material can be formed into a n instant bonsai.
Result: nice, good potential. This would be a professional way of treating it. You don't care about present beauty, only future quality counts.
Critique: This tree however, could have been looking good right away with this kind of material, without giving up future quality. I have the feeling that it was tried to make 'bonsai branches', horizontal with 'pads'. This kind of material should never be styled into a standard bonsai form. It always should have a natural broadleaved form. Typically the informal broom form would look good.
Virtual; this you could have made immediately, I believe.
Ranking: number 3 together with others
