Dramatic changes or additions however can be a bit distracting. For example adding breast to a Pokemon that doesn't have them, while not always sexual in nature it does distract a bit from them being a Pokemon. Its not bad mind you to be "off-model" Pokemon are always shown on and off model while in animation and manga and its fan art so who cares how you choose to show your art?
