Now all that remains is to paint some SFX.
So create a new layer and begin to paint.

Brushes and brush settings.





I've used basic orange and yellow color ? to paint all this- the brush flow is turned to 12 ? 14 % and the Mode is set to Screen and Vivid Light.

Final steps use a black ? to transparency gradient on a separate layer (blending mode- Color Dodge).
So we are basically done here. A little crop for better composition .and Out Illustration for the Poker machine is done ? Do not Gamble).

DIFFERENCE:





Enjoy :)!
