Sorry, but you are still not going to stand up just yet! To achieve the correct paddling technique you should once again practice on the beach and familiarise yourself with the finer points, which are:

Do - Body positioning (as in stage 1)
Do - Slightly raise your shoulders and chest off the deck
Do - Keep your head up and looking forward
Do - One arm after the other, reach forward and pull down, close to the rail, bending at the elbow and then pulling through until your arm is fully extended.
Do - Slightly cup your hands

Don't - Paddle both arms at the same time
Don't - Spread your arms and paddle wide
Don't - Roll your shoulders so much that you actually pull yourself of the side of the surfboard
Don't - Keep your head down and chin rested on the deck
After paddling a few strokes in the sand you should place your hands
onto the chest line and push up.
