When playing a druid, i find the Leaves ring not so usefull, since most of my creatures are casted from the vine tree. I usually favour the enchanter's ring, if any.
I also agree with maverick that somo more mobile creatures could be great. Raptor Vines i think are a must for the druid, i will try to include them.
I find usufull to include some more attacks (at least a couple acid balls and a couple surging wave, but pretty cheap and usefull). Also, i think you get too few incantations for both mage wands... no dispel, no teleport, no force push... I would change the defend for a rouse the beast. Roust the beast can be used to set a creature recently casted to defend, but also used for agression.
You can get the points from the 3 wands, the tripple costing Gauntleths of strenght, and some other out of school spells (vampirism, main wings, at least them can be sustituted for cheaper spells). I like to include dragonscale armour and/or elemental cloack in the druids, in order to get some defence against fire, which your creatures are weak against.
Just my opinions
