If you double click on either Sprite you will open the Image editor. Notice that the human sprite has its orientation to the right, while your canon faces upwards. Construct 2 calculates angles from the starting from the right (0 degrees) and by going clockwise you have 6 o'clock= 90 degrees, 9 o'clock= 180 (or -180) degrees, 12 o'clock= 270 (or -90) degrees...
So, within the Image editor, just hit the arrow that turns the image 90 clockwise (or download the attached file)...
Note that you could have both actions that control the angles on the same every tick event.
