I used a guide for ace attorney 3. May god have mercy on my soul.

I'm trying to suppress emotions while drawing.
Guilt, anger, jealousy, frustration, impatience.
It's hard but I'll finish something tomorrow.

Should I be rotating my canvas for those pesky diagonal lines?
I can't draw complex lines that involve multiple curves in one stroke. Should I try to get them in one shot (CTRL-Zing until they come out right) or is it ok to combine multiple lines?
I don't even care to share my works here anymore, I just want to improve.
