Plz review: AC list 1500

Should be about a 1500 list

HQ:

Command tank - Leman russ w/hvy bolter sponsons, lascannon hull, AT shells

Troops:
1 leman Russ w/hvy bolter sponsons, lascannon hull

1 leman Russ w/hvy bolter sponsons, lascannon hull

Fast attack:

armoured fist squad w/lascannon, plasma
armoured fist squad w/lascannon, plasma

mounted on chimeras w/ multilaser and hull hvy bolter

Hvy support:

Basilsk w/ indirect fire
Basilisk w/ indirect fire


Tactics: use basilisk to take out any troops, armoured fists home in on enemy anti tanks straight away, and used as a minor distraction.Leman russ take down anything - first anti tanks, then vehicles, then troops.

Should i get 3 sentinels w/ lascannons/autocannons/multilaser instead of the armoured fist squads?

Suggestions/improvments welcome
