Question regarding bank statement and maintenance

[TinaFigs]

Hi everyone.

I've applied for a visa a month or so ago and it was rejected because of the lack of currency on the statement (I've posted a topic here and got advice). I didn't bother with the admin review because my course was changed to January so it would have been pointless.

I'm planning on applying again but this time, instead of using a back statement from my mom's account, we decided to transfer the fund to my account directly so we don't have to worry about the consent letter and proof of relationship etc.

My question is: Do I need to tell the ECO that the funds in my account are from my mom? like do I need to specify the source of the money?
I'm currently working from home (not holding a contract with a stable monthly income) so I'm thinking it might be suspicious to the ECO to see that much money in my account without a real job contract.

What documents shall I provide as a proof that it was my mother who transferred the money to my account?

No.
