Tattoo ideas, will these work

Hi, My first post and it seems a cool place here so I have a few questions about some ideas I have. I already have some tattoos, some old english script and some colour tribal stuff. I think these were like tattoos of their moment, much as I love them there's not much of me in them so this time round I'm thinking hard about what I want doing. I'm thinking of 3/4 sleeves. I really love black and grey japanese stuff and have started to understand a little about having a background with other stuff 'floating' on it. I'm considering a black/grey japanese wave type of background but rather than using traditional japanese floating things, using things that mean something to me. I'd thought of them in a realistic/cubist, rather than a stylised or typical tattoo style. Does mixing styles like this generally work? I have also seen a tattoo of Nick Baxters which is finished with half tone dots which I've not seen elsewhere. Would that kind of effect work only with colour or could a black and grey tattoo work equally as well. I live in England and there is a guy not far away, Louie Molloy who is highly regarded, particularly for japanese work. Thanks for any help/advice

check out alex binny (sp?) at into you if hes anywhere near you. he has an interesting style along with the other artists he employs. they most definately could work out your idea in one fashion our another.
