Opinions on team?

All right guys, I'm about to take on the Elite Four in Leaf Green, and this is my team at the moment:

Venusaur-Lv.48
Razor Leaf
Sleep Powder
Leech Seed
Body Slam

Pidgeot-Lv.47
Fly
Quick Attack
Sand Attack
Feather Dance

Sandslash-Lv.46
Earthquake
Rockslide
Slash
Cut

Ninetails-Lv.46
Flamethrower
Fire Blast
Confuse Ray
Secret Power

Snorlax-Lv.46
Double Edge
Toxic
Brick Break
Hyper Beam

Starmie-Lv.47
Surf
Ice Beam
Thunderbolt
Psychic

Yeah, I know I am underleveled and I honestly don't care so please don't bash my team for beingso.I think it is pretty balanced and I like the way it worked up untill this point.

Probably best to go here: [Link]. You can post your team and get feedback and what not~

I'll punt it off there for you. Please check more carefull next time though as the forum section's notice and etc to state that PQ&F is for forum related queries, not team ones.

(Also maybe consider Sludge Bomb for Venusaur, Return for Pidgeot (and maybe Steel Wing?) and you'd want to drop Cut for Sandslash.)
