I'm new to the game development world so here's my question. My current workflow for getting my characters into Spine is consisting of sketching in sketchbook with my tablet, then to illustrator for making clean vector lines and shapes, then to photoshop and export to Spine. However my images never have that crisp clean look like Spineboy does. Are their any digital game artist out there that can give me some tips/pointers as far as starting resolution, file settings, ppi, tools to use illustrator/photoshop ie. "make pixel perfect", smart objects? Just looking for things I'm missing to make my characters look a little less blurry and more crisp and so that I will be able to use them across multiple mobile platforms iOS and Android devices.
Thank you for any help/advice.
