Using your picture to start with
1. I color to alpha it to get rid of the white background.
2. Right click on alpha to selection. So only the number was treated.
3. Opened up GMIC and used 'Hair Locks'. Found under Rendering.
4. Then used ML Bevel reflect - in the dialog that opens. Put smoothing 1, Round 2 Depth 20
Normal Map.
5. Unfortunately this will color the whole layer so if you don't want the background colored - select outer area with the fuzzy select tool - and cut, then export
