From left to right...1) a japanese maple I've had in the ground for about 5-6 years 2) a collected hawthorn (it made me bleed while wiring) 3) a recently purchased plum 4) a collected barberry (found it amongst my shrubs)
Your wiring doesn't look too bad for a beginner. Just remember, except for special exceptions, the wire being used should be 1/3 the thickness of the branch its being applied on (unless drastic bending is required).
