I hear ya on the great ideas coming at the wrong time. I have been pushing myself late hours with a lot of the drawing/art contest stuff here on steemit. During the day it's "work" and nothing comes to me, then just before bedtime the ideas roll in and I know if I don't start on at least getting the rough ideas down I will lose them by morning. Many times I just power through and suffer the no sleep hangover the next day. :-)

Also, If you have a single bulb lamp you can put next to you or behind you , then shorten the shutter time, it will give a cool dramatic effect. You did good.
