The clutch is hydraulic and will feel a lot lighter than before. As they get old the feel of the pedal gets heavier. You should be putting your foot all the way to the floor to change gear anyway. If however the biting point is too low to the floor then you should take the car back and ask them to bleed the clutch. Obviously it will still bite lower than before as the biting point gets higher when the clutch is near the end of its life.
