My first entry into my personal project, The Redwall Villains Challenge, starting with Plugg Firetail from Triss
There aren't a lot of references of him besides a small illustration and a vague description of his basic features in the book, so I sort of had to wing it for a lot of things.
His coat boasts some wear and tear and filth, his ax features war scars, and of course his signature firey tail. He was really a joy to bring to life.

Might I suggest tinting your lineart more? (At least in regards to an image like this which evokes dramatic lighting) You already have the skill in your toolbox, judging by the tail.
