I want to make it look like the stickman has banged his head on the hovering object to do this use the>>>MOVE TOOL to move it up slightly and closer to the hovering object>>>EXPORT AS with a different file name when done. You may want to move the stickman closer to the object and>>>EXPORT AS with different file name before doing any of the this step.

Repeat >>>STEP 15 >>>EXPORTING AS  each time you move it up slightly and don’t forget to rename the file I did numbers so this one will be >>>3.jpg or >>>3.png and so forth. Do this until you finished animating the sign in this case until it’s in the original position.

>>>TURN ON the>>>JAGGED EDGE LAYER by>>>CLICKING on the>>>LAYERS EYE SECTION>>>The>>>FIRST or>>>SECOND LAYER in the>>>LAYERS TAB on the>>>LEFT HAND SIDE and>>>EXPORT AS with different file name.

Experiment with>>>COLOURS>>>BUCKET FILL>>>TEXTURES and>>>FILTERS to taste>>>EXPORT AS each time you changed it.
