Just started learning how to sweep and I've sort of got the basics but it's still sloppy as hell, if you could watch this vid and give me some tips I'd be grateful

Sweep Picking
Ibanez RG3270M Prestige
Gibson SG Standard
Fender Mexican Strat w/ Kinman Woodstock Pickups

Vox Valvetronix AD120VTX (soon to be a Peavey 6505)

Ibanez TS9 Tube Screamer
Dime Cry Baby From Hell
that's pretty good and all, just practice really..
I run my blade through your tendons,
you scream as i watch you fall.
Squealing in your lake of blood,
i smile as i watch you crawl.
yeah, i don't even have to watch the video to tell you, just practice... i still don't have it down... but i don't practice it that much
My League of Legends stream
The morning will come
In the press of every kiss
With your head upon my chest

Where I will annoy you
With every waking breath
Until you, decide to wake up
