Color by Numbers - Vehicles

My son loves this app, as do I. However, when he finished his first picture he was so excited and asked if he could send it to Grandma. It would be nice to add a feature to send a completed picture.

I love to color mandalas and other adult/complicated themes, but this just let's me checkout and color without thinking. I only need to concentrate on the numbers and that makes my head happy. But there seem to be a few glitches. Some zones will not take color, not the color assigned or any color, so it does not register as completed. But the good outweighs the bad at least in the free version. Now that I have the full version I'll know more.

Haven't found a spot to save.
