My most recent prototype was a mobile RPG maintaining a nice bright cartoon style. Below are some screen grabs of the environment and battle UI and further below some character design ideas. Since I specialise in animation I almost never get the opportunity to delve into illustration, character and UI design so this was a rare treat and a big challenge for me.
Some Armour concepts. My idea was to differentiate the armour mainly through colour, rather than detail.
Some Animated giffs
Some further character and style concepts
