Here's a temporary ref sheet for one of my OCs, Ryu. Yes, his spikes are shorter than most Lucario's spikes.

I'm looking to get a better ref of him done eventually by someone else.
This was done at least a year ago. Started off as a sketch which then got scanned and flat-colored digitally.

Artwork done by me, and the character depicted within belongs to me.

Lucario belongs to Creatures, Inc., Gamefreak, and Nintendo.
