[Can I ask buyers to leave me a review?]

Hi all!

I have a client who made an order from me a few times already. And he loves my work, but he never leaves a review for me. So, I am thinking about whether should I kindly ask him to leave one for me. Like, I appreciate it if you could leave me a review. Once again, thank you for your order. 



But also, it seems asking for a review is against the TOS and some people said if you don’t ask for a 5-star one, then it should be fine.
There are too many answers that I don’t know what should I do. 

Thank you for your answer!! 😄

[Any tips for getting clients?]

Hi all,
Any tips to get clients 😞 ? 
I became a seller a few months ago and was not active, but recently I started to focus on freelancing again, so I returned to this platform and did as much design as possible to present myself. 
Also, I did compare myself to the competitors, how much they cost etc. But my impression didn't increase a lot. 😞 
I appreciate all of your answers!!
