It's not bad, but you need to fix your fonts. Sizes, outlines, positions, or shadows are not consistent across the entire UI and it drags the quality down a lot.
You should also consider hiding your minimap buttons.
Also, while a matter of preference, since your unitframes are really big I'd consider using a taller font like Semplice if you want to keep with pixelfonts or a condensed sans serif font. I've always found it awkward to have really small fonts on big elements.
