Asking a client to end the contract after all milestones were delivered

[webwebby]

I’ve recently completed my first contract (fixed-term) for my client and he’s so happy with the final milestone delivery.

It’s over 4 days now, I was curious if I shall ask him somehow if he needs more from me on this contract? If not, he marks the contract as completed and rates my work so it can go live on my profile because, since it was my first project on UpWork, I need rating when I bid on other projects.

Please guide me if this is ethical and good words to request the client.

Thanks.
