I like this list more. would change for a doom seer (as was said, not a lot benifits from guide, and only the scorps for fortune, and if they advance deploy your seer will be a long long ways away for them to benifit from him, where as doom has range and benifits the bikes, scorps, and DA's (aka most of your army) in a HUGE way.)
with the extra points, a missile launcher on a serpent wouldnt go wrong, nor would an extra scorp (they are your primary assault, they WILL draw fire.) Shimmer on the Avengers would also be nice as it gives them a 2ndary roll to tarpit for the scorps, also, the dragons might do with an extra guy or two, just because they tend to explode with the vehicles they shoot at, not to mention your opponent will WANT them dead in a huge way..
personally, the bikes are fine. yes for sniping, 2x3 is better than 1x6, but if you dont want to be giving out the KP, this should be ok.. just be careful where you put them and be concious of assault troops/return fire.
Food for thought: you could try 4x bikes + 1 cannon + 1 warlock + emboden + spear. (141pts) this is a little better for armor hunting, but much less survivable (has to get closer for the spear), possibly slightly less likely to run (emboden vs 1 less model)..
with the extra points from this you could afford another EML or more of the above mentioned options.. all in all, I like this list alot.
