No useful suggestions - I just understand what you mean. The problem you brought up is one of the reasons that I have not had DD take any art classes or art camps or formal art instructions. Technique is important but I think it can get in the way of innate talent if imposed at too early an age. I would continue to innundate your DD with all kinds of art through museum visits and free creations in all kinds of medium. I think this is something that she may be able to work out if her interest continues.
