I mostly want to hear how I can improve my writing. Right now, after I wrote Death-ridden, I didn't feel that it was decent enough. Hell, I thought that for most of my stories. So, how I can improve?

From the title, you'd get what I am doing. I am not done with Tenor yet, he is going till Anon-a-Miss or Backstage Pass territory. I want to know from other authors: How do you all manage your time? I am mostly busy day to day with school and extra classes. I need some help to sort out time to write.
