Super cool to see how well the video was received--thanks, all!
And, ha, yeah, sorry for giving this sort of stuff away about the character. Feel free to "hide" it as needed, lol.
NotLiuKang, yup, if you're using V2 you can end blocked strings in his projectile to create some mind games since the MB of it is safe. The first projectile is a high though and so I don't think it always jails (haven't fully tested). So, depending on the string and the level of the opponent, you may not always use it, but that's not too bad since the primary strings you'll use with Spawn aren't punishable.
CasualPlayer, after hitting with command grab, you'll either want to zone or dash in and attack, usually based on your bar and the opponent's tendencies on wakeup. His stance should be used to end your strings that hit for max damage mid screen and corner combos, or you should use it in neutral to footsie and cancel, or when the opponent really isn't expecting it cancel it after you string is blocked for continued pressure.
And Kindred, thanks for the kind words. Made my day!
