Is it a comma splice if followed by an incomplete sentence staring with an 'ing' word? I don't know exactly how to explain this properly or clearly, so I'll put up a few examples. I have seen it a lot in online writing, but that doesn't make it right. Would the following be considered incorrect:
Jenny replied, forcing her eyes away from his.
Michael put on his skates, slipping his feet in carefully.
I held the cone above my mouth, licking up the dripping cream.
We hurried home, jumping into the car without looking back.
Sometimes I don't want to make two sentences or use 'and, so, then, etc'. What should I do in that case?
