Head Explosion VFX

I'm looking to explode an actors head with 3D VFX for a single shot in a short film.

Here is a summary of everything I need for the effect-
1) Smooth transition between the two takes at 00:06 so there is no blurry overlap and it can appear as one seamless take. Currently there is a crossfade and some masking to try to hide the transition but it needs improvement.

2) From 00:09-00:14 the actors face needs to swell with his eyes growing in size and his face proportions distorting until everything is bulging and large. The idea is to have his head building with pressure before the explosion. For the bulging eyes we will composite eyes from pre-existing footage that I will provide. Currently the footage has a lens distortion effect to give an idea for the look.

3) At 00:14 his head will violently explode. Stylistically want to channel the look of the practical effect in the film 'Scanners' (reference attached) and for it to happen quickly with his head balooning and bursting with eyes popping out, brains exploding and blood shooting out of his neck.

Attached is a visual breakdown of the Scanners style reference for the head explosion and you can see the clip of the film that needs the effect at this link with timecode: https://drive.google.com/file/d/1RwLfDZ1z9cg9DVc7ANpgCM1Aln0epbb1/view?usp=sharing

The deadline for this project is March 10th and will need final files in ProRes 4444 (4096x2160). Please feel free to reach out if you have any questions.

Thank You
