I'm happy to be approached with anything, let me know what you have in mind!
With illustrations and design work I, once contracted, I usually offer three comps (rough renderings) to chose from, and allow adjustments to be requested at that stage. Once a comp is finalized it will be followed precisely in the final rendering. (Requests for dramatic changes after comp approval will require an additional fee.) After that, some clients prefer me to go straight to final, others to check in halfway from comp to final. Minor adjustments can be requested up to the end without any trouble. I will continue tweaking and refining until I have your full satisfaction!
