Heya Izzy, welcome to the wonderfully wacky world of YWS!
I love your taste in literature, because those are all excellent books you've mentioned. Philip Pullman has an interesting idea on life in his books and I like to see that older minds can appreciate his work, because I think that's what the audience of His Dark Materials was meant for.
As for your question, I'm not so active in the Art and Photography forum, but I believe that it costs nothing to post a picture, but as long as you're submitting your work, it will cost 150 points. It will not cost points for individual pictures but rather for the post as a whole. You can post as any pictures as you like, but be reasonable. Also, make sure your pictures aren't too large, or it will take forever for other members to load the page and review your work.
After you have reviewed two pieces of work, you may post whatever you wish to post, whether it be a picture, story or poem. It doesn't have to be a picture.
If you have any more questions, would like a review, or want to chat, feel free to PM me.
