You certainly look like you're on the right track. I'll second the advice you are getting suggesting not to overthink things, as counterintuitive as that may seem. With a good artist, you can leave much of the design work to them. Also, a lot of the traditional photos you have provided would be best (in my opinion) with at least some color. Although I have to admit I have a strong bias towards colorful traditional work. Bold lines and strong colors seem to work pretty well and hold up over time. There is an excellent thread on these pages about what makes a good tattoo and the consensus seems to be that strong black lining and good shading forms the foundation of good tattoos. Color just adds a little extra spark, in my opinion. Not to mention, browsing through the various galleries here will demonstrate the truth behind that sentiment. Best of luck to you in whatever you decide. Looking forward to seeing how it all turns out.
