Correção de texto: How good my english?

I'm just getting started to learn English. I've been studying really hard and I think I am evolving week by week. So I want you to answer me: Is this small text ok? I mean, is there any mistake in it? (I suppose there are tons of mistakes)
So that's it. Thank you all.

My stab at it.

How good is my English? or How good do you think my English is?

I'm just getting started to learn English.
I'm just getting started with English/...getting started learning English.
(my opinion is that would be more natural this way, but let´s wait for more opinions on that one.)

So that's it, thank you all.
(it´s just my style here, I wouldn´t separate the two parts.)

Overal your piece of text is very good, you are really off to a good start!
Congrats on your writing skills.
