Very good start, and as Barry posted a bit of sanding and hay presto.
I note that you used spiral blades, I have been scroll sawing for many years and the one blade I have never had any success with is spiral, just a thought.
I always use a stiff polishing brush to remove the fuzzes on the back of the work, found that to be quicker, easier and more effective than trying to fiddle around with sand paper.
Suitable brushes for this job are polishing brushes used for wax finishes and can be obtained from any of the woodworking tool suppliers.
Take care and enjoy your scroll sawing.
Chris.
