why u color the edge with grey?

The characters seem cool and nicely drawn (I love what their wearing), though I'm not too sure about the filter over it. Makes it kinda look low-quality.

It's always nice to see a change of pace in an artist.
Though the style is slightly different from your earlier works, there are still remnants of your earlier designs. To me personally, I think your work have grown closer to realism.
It's a good sign, when you’re taking new things into account without discarding what already working.

Proportion wise, the girl with the blue eye appears to me to be the more successful ones. However the hand from the yellow eyed girl on her neck creates separation in between her body and her head. My eyes lead me to believe that her head is larger than her body.

Now when you think you have understand the proportion system, you should see more on how human body movement, to create real posture, as the yellow eyed girl appears to be very misleading to me.

Perhaps planning the posture with stick figures might help you, and also looking around for human activities, basically you need to see more on how the body moves.

Good work on the shading, however to my personal taste, I prefer without filter. I can probably understand why you chose to filtered it. To me it is important to keep the pencil line clean at all time, don’t worry to make mistake with lines and always keep your pencil loose, don’t stress it out.

Overall it’s a good work, keep it up. Next time it might pay to be much more relax with your drawing, instead of following the formula create one from your mind. Ok that’s all for now, have to go back to the office n.n .v.
