These are great, I wish I had your talent. I love the expression on the guys face in the last picture especially.
Your proportions look good to me. The girl in the 3rd & 4th drawings shoulder looks a bit odd, but other than that I think your line art is very good. There is one thing that really bugs me though, the chain-mail texture in the second to last picture. It looks a bit out of place, and flat in my opinion.
You're a very talented anime artist. All of your proportions are great, and your details are wonderful. Keep up the good work.
The coloring on the shield in the second to last pic seems a little flat though.
The hands are good too, but you should also work on the feet. The boots on the lady with the Halberd are oddly shaped.
Also, the shoulders on the first couple of pics look a little thin, but overall, very nice.
I like the style; it's cute and there's nothing glaringly wrong with the pictures in general. Even the arms are satisfying except for the one on the shield - but arms are a bastard to do right perspective of anyway and I can't really say what kind of correction, consider how much I suck at them myself -_-; But otherwise the pics are quite enjoyable.
