crab2selout >> very interesting edit. You did lose the character somewhere along the lines of doing it, but even despite that the design stayed strikingly similar, and has also inspired me to try and make a new one.
A lot of the issues resulted from the fact that the sprite is essentially the umpteenth alteration of a sprite that was originally around 2 years old, and due to the fact that the more and more I edited it, the more and more I felt 'constrained' to keep the alterations minimal and within a certain style. I couldn't bring myself to edit like things like the front of the vest/coat for whatever reason.
I decided that the best way to try and remedy the situation was to simply start from scratch again.
Thanks to both crab2selout and Helm for responding and critiquing.
I decided to try and make a new version of the sprite due to general dissatisfaction with the original. I'm not really happy with how its coming out, though; I'm trying to get a somewhat stoic/reserved stance and form, without making it too lazy or alternatively too 'stern'. In general I'm not sold on the way the legs and upper torso are connecting. It feels as if there's some kind of anatomical perspective issue going on.
I've made it larger, and in the process somewhat taller. I may end up making it a little shorter, though. I've varied the palette a little more and increased the contrast and tone slightly, although I ended up slacking a little bit on the 'reusing shades' aspect of the shading brought up before.
I'm most conflicted about the head/hair, and the legs.
C+C and edits would be heavily appreciated!
EDIT:
Slightly altered version. Red jewels on the knee pad return, better leg design imo and a few minor improvements. Something still feels off though.
