Progress - I used pen tool to create this image. Issues - I'm not sure how to use layers well. Is the first layer the layer shows on top?Goals - I hope to learn more tools in Illustrator and be comfortable using it.
I agree with Emily, and I think maybe you can use the direct selection tool to drag each object together so there's no gap between them.
You trace out each object clearly and choose the colors accurately. I think maybe you can pay more attention on details such as the connect part between two objects.
