I think your English is excellent. You spoke fluently; I didn't detect any grammatical errors; and everything you said was completely understandable. The only "problem" that was noticeable to me is that on two occasions, you mispronounced an initial "w" like a "v". The two words were "where (I stand)" and "what (I did)".
You speak English with an accent different from mine, but that is no problem. From your perspective, it is I who has an accent.
Keep up the good work!
