Your character list is solid. Though I might give the priest on the EOTG some items (plaque of tepoc to make him basically a lvl 3 mage). And I like cupped hands of the old one, as opposed to sould of Stone for miscasting. 20 Saurus is a bit to many, as has debated on here many times 18 seems to be the top choice at 6x3 ranks. Though I tend to find 15 works better for me. Also a Champion here really isn't necessary. I would lower each skink skirmisher unit to 10 (unless there is leftover points to spend). Terradon Rider brave is not worth the points. Temple guard, champion not worth it unless you want to surprise someone with some extra magic items. Also 20 can be overkill as 16 works well too, but lots use 20 as well. Cold One Calvary again champion isn't needed. Overall a solid list with which I would just make some minor tweaks to. Reduce some unit numbers to get some items on characters. Also if you lower the numbers and take out champions you could also be looking at another unit of skirmishers. Personally I would try and fit some salamanders in, as I find them invaluable against most armies. edit: well then id say lower the numbers and add that priest back in
