Anyway:
i) Double mould line on her face and awful mould slip on her gun! Not your fault but shame on Reaper

ii) Elbow as already pointed out.
iii) Skin: looks a little drybrushed and uneven. I'd go for solid blends rather than dry-brushing, (it's a falacy that it's a quick way to paint, great for wood grain, bases etc.. no skin).
iv) Reds: Well I always paint reds a bit too dark and build up, it suits the minis though, (have a habit of painting plate armoured chaos dwarves red

). Just avoid going too pink on your hi-lights and do subject subject analysis, look at how red clothes take highlight and shade:




Hope this helps, (took me ages to get red right!).
