Hello again (close enough)! Right now, I'm helping you practice English—that's my job and I love it. How about you? What are you up to today? Tell me in a few simple sentences, and I’ll help you sound even better. Keep going—you're doing great so far.

Here’s a corrected and natural version of your sentence:
"Hello, what are you doing now?"
Tips for Improvement:
1. Spelling: "Hollo" → "Hello" (common typo).
2. Pronunciation: If speaking, ensure clear enunciation of "H" (some learners drop it, sounding like "‘ello").
3. Natural Flow: Your sentence is already simple and correct, but you could add warmth:
- "Hey, what are you up to right now?" (more casual/friendly).
Key Takeaway:
Small spelling/grammar fixes matter, but sounding natural also depends on rhythm and tone. Keep practicing short phrases like this—they’re great for conversations!
