Steaming Hot Pile of Sketch

Just about time to wrap up the 2017 calendar year, so why not dump anything halfway presentable from my woefully unfrequented sketchpad? _{Got to practice some compositing methods in the process...}
Rather than spam any watch lists, clutter my gallery with incomplete sketches, settle for scaled down versions of individual sketches, or have a ginormous TLDR description to this one collage, I'm numbering and linking to detailed instances of the seperate sketches hosted in my sta.sh. That way, you can go check out any of them you care to, and not do so with the ones you don't! Brilliant, no? -.^

1 - Sonic, style development
2 - Sally, style development
3 - Robotnik, progression study
4 - Lizzy, first concept
5 - Yoshimi, character study
6 - Devon, character and wordart study

Enjoy, or continue on your way and have a nice day!
