Looks good! I <3 font unity, and I'm liking the placement of the combat text a lot.
As for what I would change... to keep with theme I would outline your lightning shield stacks (?) with that 1px border to keep with the theme. Also a lot of elements are swapping between having 1px and 2px in between them, I don't know if that's intentional or not (ex, between your target bar and the bars above it, there's 1px, but between each bar there's 2px now). I'd also maybe unify some of the icons sizes since
none of them are equal (see pic):

(that being said I'm just majorly OCD about sizing and pixels, which you can probably tell from this:
)
I'd also make your red bars grow downwards for vertical symmetry, and also bind /script UIErrorsFrame:Hide(); to something on load.
A lot of that is personal taste though ^_^ /thumbsup
