Graphic Designer with verifiable shirt design experience

Looking for a graphic designer with verifiable shirt design experience. This will be for a video game niche, which means:

- The designer MUST have experience designing game characters (anime and western style). I will request for proof to check the design quality.

- I will be providing ideas (as descriptive as possible) and requesting revisions when needed. So it's important that the designer is able to understand instructions written in english. If you know how to create original art design for characters like Mario, Yoshi, Zelda, Snake (from Metal Gear) we're on good track.

- I will be asking for original designs or a mix of existing designs. Sending me plagiarised designs will immediately end our agreement. I'm proficient at searching for existing images, so please don't try this one.

These are some example designs I would be expecting from you (I do not own these designs, just showing them as an example):

- I will expect around 12 designs per month. This parameter will also define if we should be working together or end our agreement.
