I agree with what the other community users are saying about your UI Galinn. There are so many nice elements to it - it's neat and seems like it has everything one could want, however, the pet frames are way too large. I would be tempted to make a little more space in between my party frames and just tuck them to their respective bottom right. Same thing with the target debuffs (the red squares) - if possible I'd move them underneath the target frame itself. Again, I must agree with the rest about the font, but you've already said that you'll probably change it
Otherwise - nice, very nice! Looking forward to seeing a download for it soon!
Just out of curiosity - what resolutions will you be supporting? It seems like 1680x1050 from the screenshots.
