I have a lot of problems with a control deck playing less than 24 lands, you NEED to hit a land drop each turn AT LEAST until turns 5-6 or so.
For starters, I think Bitterblossom should not be missing, it's THAT awesome. Then, you should either play a full set of Mutavaults or none at all, they're that good. I'd consider playing one more Noggin' Whack, perhaps only one single Liliana Vess, playing a full set of Bitterblossom, possibly 3-4 Mistbind Clique (could be cut down to 2, perhaps adding a singleton Oona as finisher), and probably some Profane Commands.
However, for Lorwyn Block control, you should take a look at the old UB Mannequin lists, give or take a few things.
