It looks pretty well rounded
It`s amazing how you can make an army of just 30 models 1.5k points big
Actually i really like your list
you`ve got an inquisitor, an assasin, grey knights termies, storm troopers a dreadnaught a land speeder and a land raider
Those are almost all my favorite units in the game stuck in one 'small' list
You`ve a good load of anty infantry, extra model count in the form of storm troopers which are also quite mobile, the kights and take a whole lot of beating, i trus you`ll make good use of the assassin (have no idea how well an inquisitor or henchman works) and unless you have really bad luck with the rolls you`re safe from most armor that`ll fit in those points
Good job!
