Tattoo Cover-Up Design

I am looking for someone who can design me a cover-up for a tattoo that I no longer like. It's a tribal tattoo along the bottom of my back. Pictures are attached. I am looking to keep the tribal theme, but I want a less "feminine" design. I'm happy to cover it up completely or just have it extended (in whichever direction). It's been suggested that maybe I have it reach right round to my abs, or down to hip (or both). I really am open to all suggestions as I really am not good when it comes to this kinda thing.
In the past I've always visited tattoo parlours and had the tattooist design them for me, but find that I feel under pressure to make an instant decision. Being that I already have a design that I'm not 100% happy with, I dont want to make the same mistakes again, so I prefer to take my time choosing a new design and working with somebody to get something that I really like.
I also have two other tattoos that I would like to change, so if I'm happy with the work that you do I'll be happy to put more business your way too.
Thanks a lot for reading this post, and I look forward to seeing what people can offer me :-)
