Apologies for the bare bones reference sheet. I meant to have a far more detailed one but time and work didn't allow for it very much.
That and I was so fucking anal about the designs. I swear to god I have about five or six different reference sheets changing the Digimon designs, particularly the Armor evolution since, all of a sudden, it decided to turn part motorbike and machines are a weakness of mine. x_x I'll probably work on something more updated in the future, but if there's any more questions or references needed, feel free to ask.
EDIT: Updated the looks of Yinyamon, Bipomon, Revmon and the DigiEgg of Balance. In case anyone is curious for the egg-swap, the DigiEgg carries the steel element and digimon using it tend to turn into various machine, cyborg Digimon.
