I dont really feel much of anything for miles....
and 45secounds isnt long enough to really impart the feelings you want onto the viewers.
1 scene with him playing tag, isnt going to be enough for anyone to bond with him.
Your assumeing people will identify with the character without any depth to him, and sure its a kid in a hospital after a accident but without any emotional investment from the audience it wont have nearly the effect your thinking it will.
Your going to need 4-5 minuets probably.
Theres this really good edit of "Pixars Up" that shows Ellie and Carl's relationship through time... and its just heart breaking.
Whats done so we ll with Carl & ellie is you see:
Them as silly kids, where carl has a crush on ellie. Big enough to follow along with all her silly plans.
You see her falling for him, them getting married, the wacky house drawing she drew as a kid, they buildt & painted together, the silly mail box accident with his unplanned handprints on them ect.
Then the music changes and you can feel & see the loneliness in him after shes gone, and the realisation that he never forfilled her dreams of exploration.... its just heart breaking.
** suggestion:
Take things down a really screwed up path instead. Those demons he sees, the hair of the girl turning black.... that all says HORROR! to me.
Why give him the rosey white cushioned & cheap ending? he just fades into white.
NO.
Give him a nightmare like state more than just 1 scene (maybe showcase some error he commited that resulted in the car crash? basically the demons tormenting him with his mistake that maybe killed his intire family?), and in the end impart the little sucker is going to hell or some such.
Would be much more impact full.
