That was vey good decision to make the painting with your niece, children in this age are very keen to learn, but also they are glad when they have attention of adults. Of course, when at the end there is such great result.

For this exercise both of you put your efforts, she had great idea of a subject and you had also great idea how to fulfil it. You are very good team.

I love idea of using hands as wings, it is difficult to easy and simple to get that idea on other hand it is difficult to come to this idea. The colours are typical girl colours, well done work and videos :)
