Don't take this the wrong way, your'e definitely not a bad artist, but if it were me I would find a really good tattoo artist and let him take the idea into his own hands... I know it sounds cool to design your own tattoo, but if the artist is forced to follow your design it can sometimes result in a poor looking tattoo.. I mean it IS permanent. Maybe give him your drawing and let him go at it... Just my suggestion. I have a really great tattoo artist in my area and when I took my design to him he made some changes that I would not have thought of and it came out looking great. My other friend who has been going to this guy for 10 years doesnt take designs to him anymore and just tells him the basic idea because the guy is an amazing artist and the tattoos always come out looking phenomenal. Just my $.02. Again, dont take this as me bashing your drawing or anything, I know I couldnt draw em that well (I'm more of a cartoon guy), but drawings and tattoos work very differently and what looks good on paper doesnt always look good on skin. :thumbsup:
EDIT: I went back and read your post more and realized it doesnt really sound like you were considering getting a tattoo, but maybe others that are can maybe take something away from my post.
