Sometimes there is a child who does have artistic flair from an early age.
I remember dd1 drawing alongside a younger child when she was about 5yo, other child was about 3yo. What the other child drew was out of this world. Yes, I probably could have produced something similar with time and effort, but not much better.
And also she may have a better grasp of the sort of design needed. There used to be a weekly competition in our local paper. I entered for years and didn't win ever. They did a variety of competitions and drawing was one that came up around once ever couple of months.
Then I noticed that the pictures that won were actually quite basic, clear outlines. Obviously so they could put them in the local paper to show the designs. After that I drew like that and, despite my lack of natural drawing skills, won almost every time I entered.
They may have judged it blind, or used different people to judge too.
I remember my dc between them won the craft competition 3 years running at the summer fair. One year it did look amazing as they'd had a really good idea, and I looked at the entries and thought they stood a good chance at getting something. The second year I would have put them well down the list as I thought theirs was too simple, and the third year was good but not outstanding, thought they stood a chance at placing but not winning.
They were judged by a local dignitary who didn't know the children at all, just they were lucky to hit the style they liked. The second year the chap went for all very simple designs, and the third year again the judge chose 3 designs very similar to dd's.
The other thing that I reckoned mine always had going for them was that they clearly had done it themselves. Some children turned up with immaculate pieces that clearly they hadn't been allowed within 15 paces when they were being made.
It may be that some of the other good artists have parents that can't resist making it perfect before handing it in, so they get eliminated on that basis.
