Leighann asked me to post some screenshot of my mages UI so here are some that I've taken in the last few days .

This first one came in LFR I think on Sunday.

This is from the same LFR just a little while after. Glad I took a second shot since my cast bar was missing in the first one.

Here is the last one I took in raid tonight while I'm not in combat (complete with 2 elementals)

The mods that I'm currently using are as follows:

ElvUI (Unit Frames, Raid Frames, LibData Info, Threat meter (lower right hand corner of the first 2 screenshots, action bars and buff/debuff timers)
WIM
DBM
Skada (Just for damage)
Quartz (For my personal cast bar)
MageNuggets (Just for easy of portaling)
Parrot (For my damage text, I'm considering going back to the Blizzard built in one as ElvUI will modify the text of that as well if you set it up to).

If people want more shots, I'll try to provide more if requested over the next few days.
