I have my cosplay portfolio attached in my signature if you want to see samples. I would say 95% of it is with the 24-105 f4L. I personally think it's the go to lens on full frame for everything including video because of the IS. Only thing I don't like is lack of a zoom creep lock and noisy noisy IS which can ruin some video shots if you're not recording off camera.
There are several 70-200 lenses. I have the f2.8. If you were shooting at 200mm, that's twice the crop of 105mm, more or less, plus the 2.8, giving you about 2 stops of effective extra bokeh (the physical reality doesn't work this way, but I'm simplifying it, for all the photogs who just smashed their keyboards at what I just typed).
The problem with a 70-200 for full body shots is one, you have to stand significantly further back and two, standing further back gives you a different perspective on the body compared to wider angles. This is good or bad depending on your intended composition. I tend to shoot around 35-50mm for full body shot so I can stand closer and give that more intimate feel. Do you have a sample link of a fully body shot with the 70-200? We may be able to help break it down for you as to why it looks the way it looks, especially bokeh and how far the subject had to be from the background and camera.
I personally think the 24-105 is an amazing lens and partly why I switched to full frame.
Hope that helps!
