This is a commissioned piece for someone on twitter. I was commissioned to design a character for them, specifically a genderfluid shapeshifting skulldog wizard. I was given a fair amount of freedom, and the client gave good instructions and feedback despite it being the first commission they had ever gotten. It did take me a while to work my way through- longer than it should have- due to homework and moving. There are adult versions of this sheet out there. Be warned- if you go looking for them, you will see adult content. I claim no responsibility for you seeking that out, and will hear no complaints or derision about that. I was given a job for money, and I fulfilled it in my professional capacity. That's an absolute necessity when working with adult material!
