Kingpin & Lex LuthorvsElektra & Lois Lane

Kingpin & Lex Luthor Good start to editing. I would suggest Adobe Photoshop so that you can chisel away certain white spots around parts of your picture that you don't want.

Kingpin & Lex Luthor If you want to use Adobe though, just put in both images, drag the one of the guy getting stabbed where you want, rasterize it, and use the lasso tool to carve away the white spots of the guy getting stabbed, so that there isn't anything blocking the blade in the last image. It'll look cool. I know it sounds complicated but it won't if you get the hang of it. Anyway, it's a good start.
