how do people come up with tattoo sleeves?

i want to get a tattoo sleeve, and i have been looking around on the interent for inspiration. I really like sleeves done by Nick Baxter. How do people come up with sleeves that look that good? I am not good at drawing at all, and I want a sleeve that looks similair to the other sleeves nick baxter does, I wouldnt copy any though. And I dont want a stupid one like knots or tribal, or any flash s''t

Anyone know where to find good tattoo sleeves for Black People?

I love the tattoo sleeves that are out now...Ed Hardy has the most popular brand, but there are many others. Only problem is, most of them appear to be created for light skinned people, and my complexion is medium brown. Any suggestions on an option for me? Much appreciated!
Note: I'm referring to the fake tattoo sleeves that are worn as clothing, not a real tattoo. Thanks!
