How's your English?
I need more casual questions when asking people (in Chinese) if they speak English and then common follow-up phrases. Can you help me find basic equivalents for things like:

* How's your English?/How's your English going?/How's your English doing?
* responses for "bad": Don't worry/Don't sweat it; I guarantee your English level is higher than my Chinese; between your low English and my low Chinese, we'll work it out

Other suggestions?
