Inspiring a character

At the moment we keep changing our mind about our main character every 30 seconds, hell we cant even decide what species we want him to be, troll, goblin, or human. I feel that if we can pin a character that will help us establish the environment he lives in what his weapons would be and what the story could be like.
So following the goblin/troll theme ive set up a few images for inspiration and reference in the hope we can pull something out of it as a basis for this character.

I personally really like the larger creatures especially as they have melted into the forest and merged themselves with nature over the years.

Again i personally would love to see plate armour but made out of wood and bark held together with leathers and belts with maybe a mask covering his face.
