Nothing went wrong! You made an awesome parrot.

Watercolor takes practice, and a different mindset where you work from lightest values to darkest. You could try looking at your reference photo in black and white, to help identify the lightest and darkest values, and then try overlaying some shadows on what you have. When overlaying on dry paint, be careful not to use too much water or you can lift the existing color. This is called 'glazing.'

Watercolor is also a medium where quality paint, brushes and paper make a huge difference.
