Hasta La Motion!

i need some idea here, i got shot as a clean plate_BG ( i give u as an attached file )–then later i will do timelapse painting on the wall–just like in dulux-lets colour commercial. so my question is , what is the better way to achieve this shot ? should i do camera projection after i finished timelapse painting element ?:confused:

im just crossover from flame and inferno..so this is my nez experienced in nuke.

ok i need your suggestion about my case. thanks a lot and i appreciate it whut ur concern.

cheers
