Ah, the chest... It was more a reference to the wing muscle style stuff that some dragons do (where the muscleridge goes over the arm) but since it doesn't have wings, I guess it looks weird.
I have issues with the chest since Im not sure how the arms would join the neck on a dragon/dinosaur/lizard.
Fahrenheit: The main reason for the change was a lack of focus - the leg was commanding too much attention, and changed the belly too because to me it felt really unfinished and it was inconsistent with the tail's texture.
Im not sure what to do with that either, don't really mind the oilyness. Its easy to rationalize either texture, oily smooth or rough pebbly.
