Very nice Zack drawing. It is good to see his old school design make a return even though I enjoy both renditions of the character. As always you have a great dynamic presentation in terms of character positioning and expression. I do love your gritty metal background/textures.

I also understand where you're coming from in terms of changing or "mixing it up" with your original character(s). I have the same problem when I go about redesigning Omarr with his different outfits and alternate costumes (not to mention his "clones".) I figure as long as you maintain a sense of consistency with the character's personality and development history, you'll always enjoy creating projects with said character while experimenting with different things.

Keep up the great work bro and I hope you appreciate the critique.
