you're at 491 points, not 501
right now you're lacking anti-armor weapons, aside from the hammerhand (which is CC only) you don't have anything capable of piercing even armor 12.
your squads are kinda small, and prone to being shot to death before you can get them in close combat. if you get rid of the psycannons you'll be able to expand your squads, even adding melta bombs to your Justicars will give your standard units the possibility to damage armor in closecombat without having to seek out its rear armor.
master-crafted weapons are a great option, but you're spending almost 10% of your total on it. for those points you could add more knights to your squads or if you got ride of your psycannons you'd have a total of 129 points left to use. for that you could buy a dreadnought w/ assault cannon, missle launcher, extra armor, smoke launchers and still have a point to spare.
if you ditched 'Hammerhand" as well you'd could enough points to buy a 3 man terminator retinue to go with your HQ, give one or two of them thunderhammers and you've better odds of punching through tank armor than 'Hammerhand" alone could.
Edit: its not a bad list by any means, just it will have trouble catching its foes to get into close combat and with the armor problem(common for all grey knight armies) For a new player though, its a pretty good list to use
