my comments
here are my comments on your work.
they are negatives and positives comments
- I don't really see the goal of the alter environnemnt.
Most of the effect described can be obtained with other spell list (evoke area or abjure...)
- Alter size. can be done with polymorph [creature] or polymorph [biomatter] (if we accept that living creatures are made of biomatter element). Anyway, the strengh bonus is far more too important in comparison with the PHB spell (enlarge) that limits the size to 150% of the original size and gives +1 STR bonus for every 20% (so you can get only +2)
here how I would have done this list
lvl size increase STR target duration
0 10% 0 perso 1r/lvl
1 10%/level (max40%) +1/20% 1 1min/lvl
2 10%/level (max60%) +1/20% 1 1min/lvl
3 10%/level (max100%) +1/20% 1 1min/lvl
4 10%/level (max40%) +1/20% 30'radius 1r/lvl
5 10%/level (max60%) +1/20% 30'radius 1r/lvl
6 10%/level (max100%) +1/20% 30'radius 1r/lvl
7 10%/level (max40%) +1/20% 30'radius 1min/lvl
8 10%/level (max60%) +1/20% 30'radius 1min/lvl
9 10%/level (max100%) +1/20% 30'radius 1min/lvl
this list should alos be used for "reduce"
- control gravity effect can be obtain with the infuse creature with air, sonnic and few others (fly, feather fall)
+ Dazzle sound good to me
- distotion . U shouldn't give a better bonnus than "blur" at the same lvl.
+ Element shield. A must. I would have increase the rresistance to opposite element. (something like elemental protection. i.e. some hitpoint/round with a maxium that can be absorbed). aout damage, if the weapon is metalic, heat and electricity damage can be conducted to their wielder even if she/she have a reach...
+ Hand magic. sounds good too.
+movment is a must aswell. but haste does not gives a bonus to reflex save. it gives a +4 Dodge ac bonus. and you might prepare for the 3.5version and says that it gives only one bonus attack (instead of one partial action)
+polychromatic is good too
+telekinesis is ok
- light and shadow can be done with infuse object with [element]
-silence can be done with abjure sonic ?
In conclusion. you have some very good ideas that need to be precised and, most of all, reduce in power
