I cannot say this enough to people:

reference photos are your friends.

There's no point doing structuring if you're not using anything to inform your drawing in the first place.

There should be a bit more thought put into your structuring than just drawing a couple circles. Do they actually help you in any way? Did you particularly think about how they're positioned or how different parts interact with each other?

Also seriously
when you're a beginner you don't particularly need high-end materials. Start small and work up.
