*Critique please* I did this still life today, and I think some of the elements look weired, but don't exactly know what. How can I improve it?

If my life was a movie it would be an adventure, fairy tale. It's about a girl who one day finds out about sea dragons that live in the ocean and protects the ocean .She decides to draw a painting of it, and suddenly she is sucked into the painting and there her journey begins! Hope you like it ,really exited for the challenge :)
