Or is it normal?
I feel like I should be worried as it means that he hasn't achieved the necessary standard for the learning goal and he is an autumn born too.
It's for Expressive Arts, music, dancing, playing with different materials and media etc. It's probably true that he is not really into this kind of stuff (although he does listen to music at home and enjoys it and he goes to a dance class once a week and enjoys it although he has got 2 left feet..he hates colouring in kind of activities though) at school and chooses to play with cars/role play kind of stuff rather than choose to do that. Does that mean he is not acheiving the required standards? He draws quite well though when he does do it.
I'm personally not that concerned...perhaps I should be?
