Tattoo ideas drawn

I have several screenshots of things I would like for them to be drawn up all together to make one tattoo. I will also need to add a hand drawn piece from my neices when she finishes it. The artist I choose will basically have free reign on putting it together as long as it includes my requirements. I just want it to look good once it's all together I know that it's going to end up being quite large. I will give more detailed information to the artist I choose.
