DOTA Allstars - Stand of the Heroines

First of all, we can all praise your incredible work of precision on each character design. I don't know so much about them since I stopped following the Warcraft series after Frozen Throne but the amont of details is wonderful. Plus I love how you depicted the different personalities for all of them, in their facial expression and attitude. Not to mention that beside the precision, you drew them greatly in a very elegant way. I just think that Lina's arms look a little too long given her pose. I also love the sepia look of your drawing, as it it was an old scroll showing warriors of ancestral legends. And you surely have a very good use of foreshortening.
However, your drawing gives the feeling that it misses something. For example, a background would have given your drawing more impact. Not a full background because the details of the characters would have been less enhanced. But just a few elements would be enough and it could echo with some old black and white Warcraft 2 artworks. Alleria's body (the one raising her bow on the left if I am not mistaking) unfinished under her waist looks somewhat odd here.

In a word, your drawing is very beautiful and pleasant to watch but you stayed in your comfort zone. Since you have awesome skills, you could easily make something even more stunning.
