The correct translation would be something along the lines of this:

"Don't even look at me. I'm much worse at teaching idioms that at painting... And I really suck in that.

By the way, why would you need it in the future?"

Not exactly word-for-word translation, but that's the problem: Google does it word-for-word and often fails at transmiting the message's intention.
