Well the one and only tat I currently have I got back on Canada Day 2000. I drew it myself, which is of a slightly Goth-like maple leaf, which is black, with flames around the top, horns coming from the corners and water rippling below the leaf..... it is on my left arm which created it.
It's not super fancy, as the last design I made, I was told it was too complex *psh* so I perhaps over simplified it..... although the various colours in it do help balance it out pretty well. I do plan on adding to it again someday when I have more money to burn.... hopefully to extend the whole thing to go up and around my shoulder and down around my elbow.
After that, I may have one more tat on my other arm, but that would be about it for tats.
What you could do is take those two pics, print them out and goto a Tattoo artist and tell him/her what you want done. They will usually draw out a template they will use to apply to your skin, and you can go back and forth figuring out the final design.
Or you could take what you drew already, they will retrace it into a template, and away you go.
Just remember that the more colours you add into the design, the higher the cost. Mine has..... um...... 6 or so colours in it, is only about 4"x4" in size, and cost me around $165 for the whole thing.... where if I just got one colour with the black, it would have only been about $80.
