Yeah, I see what you mean. What messed me up there was the Calf muscle, I pictured a flexed muscle from that pose which makes it pop out more - so I intentionally made the knee joint smaller than it should be to get that point across. hopefully that makes sense.
aside from that, somebody else in the FB group pointed out the hand size difference, which I hadn't noticed as well. for that I had the right hand sizes but I hadn't modelled the gun yet. so when i found the shape I wanted for the gun and created the hand around it. I'll have to remember to watch out for those mistakes in the future.
Thanks for the feedback. Julia
