I would agree with Ikarus and Typher. Your points distribution is a little off. You have more than 1/4 of your points on your HQ choices! Bad! You should have more on troops than anything else, and only about 10-20% on anything else! This makes for a more balanced army, unless you have a special fluff thing in mind, or you really know what you're doing. Which you may, and you did say you did fairly well, so that may be the case.

I would grab a predator with triple lascannons. That will give some long-range punch and be able to stand up to a little more than a dreadnought.

I would also ditch the LRC. I'm guessing you put the Termies in there, but I think you can deep strike them or, since they can shoot, just walk them across the field if you're not against Tau or IG. They will be able to dish it out as they close for assault and provide another scary target on the board.

And as for Honour Guard, yeah. Death Company and assault squads is all you need. Only add them if it's a huge battle, or you just really want to use them. Use sparingly. Like energy drinks and medicine. Don't OD.
