Nice z-sketching. I can't see if the character is coming or going at a glance. You have a lotta stuff everywhere. I searched for a youtube video I have seen on balancing detail but cant find it, have a look for something along those lines (including silhouette) as its going to help readability of your work. One thing you don't see much of these days is artist putting up a sketch for reactions and feedback, then actually following reactions to realise a well rounded piece. Good luck!
