You need at least Internet Explorer 10, or you may want to give Firefox or Chrome a try.
I prefer the Red X part.
Maybe next time you can use the select option to select the half part first then draw the picture will have a better result on splitting drawing. Try more different function will help a lot on your works.
Drawing is about studying yourself and your target.
Thats's really good advice. I'm actually doing a split drawing soon so ill try those out. I'll also leave it so people like you can variate
Thanks for the comment
