Hi Ana, I understood what you said. Your Chinese is not bad! A little more practice on the tones will be better, especially the second and the fourth tone! I am sure you can speak very good and fluent Chinese if you keep practicing!^^ ni3 hao3, wo3 jiao4 an1 na4, wo3 shi4 a1 gen1 ting2 ren2. ni3 jiao4 shen2 me ming2 zi4. zai4 jian4.

Even though I am not a native speaker, I can say that I understood all of it. Although with "什么 shen4 me", you over emphasise the "n". Make sure it doesn't stop the flow of the entire sentence. So, basically, go lighter on the "n" in shen4 me.
