The fighter levels help to maximize the number of feats for this character to take. The level in Dervish allows for the scimitar to be treated as a light weapon and thus applicable for weapon finesse. The 4 levels in Tempest allow for the penalties of dual weilding light weapons to be reduced to +0/+0. Without other equipment and masterwork scimitars with a +1 weapon enhancement at level 20 your attack rolls on your main hand are +31/+26/+21/+16 and your off-hand are +31/+21. your crit range for each scimitare 15-20/X2 with a +12 to your confirmation rolls to confirm crit on each weapon (+13 if your weapons are made of Solarion Truesteel). This will greatly increase your chances of confirming your critical threats.
Perhaps make scimitars Tempered Steel (d20 toolbox) or Laminated Steel (Mercenaries) to increase crit rate to 5-20/x3?
This build is great for slashing enemies to ribbons with the ability to crit so often. It may seem to be weak obviously to undead and other creatures immune to critical hits, but if you have burst enhancements and other similar crit trigger enhancements they still apply. If you threaten the crit, you still roll to confirm. If the crit is confirmed, you don't roll extra weapon damage but the crit trigger enhancements still go off. It may not be great during the early levels but you could progress as you wish until you hit 7th level and then retrain your feats to meet the prerequisites for the rest of the progression.
With the low reflex and will saves, The DM could use many explosive or mind controlling type effects to help counter your deadliness. Or the DM keeps combat to a minimum in which case this build wouldn't be that effective.
