I am new to adobe stock and I can't figure out why this illustration was rejected. Thank you !

You chose some pretty difficult subjects for AI. When it comes to laptops and computers, I try to come up with examples where the camera sees the laptop or computer from behind. This hides the keyboard and any hands that might be incorrectly rendered. 

The drawing errors are easy to find - gibberish text, melting keyboards, poorly drawn hands, too many fingers....

What was the refusal reason? Did you check your assets for quality issues?
