nice take on it!
And trust me, being a Bishop Steiner is not all it's apparently cracked up to be! Now being a Flying Debris, or Shimmering Sword.......
That said, good works. And the only way to get better is to keep practicing, keep posting and keep listening to critiques. With a little work on dynamic posturing, and the little things, like consistent scale/proportions, you will be off to the races! Basically it's just lots of repetition. But always good to post, and if ever you do have any questions, or run into an issue that is stumping you, tossing them up here is a sure way to get valuable input. I've certainly benefitted from some (even some painful stuff) from CarrionCrows, Shimmering Sword, Alex, TG Xarbala and many many others!
