grey shading

hey guys got a problem and needed some advice i i have a full sleeve blackwork ( tribal) tattoo that was done about a year ago I went back to get some shading done , I just wanted some light shading with a few sort of highlighted black areas ( i wanted this done on all the areas of my arm that were not inked in black ) so this artist done the job and assured me it would heal up right , i looked after it and had done all the required aftercare. It has been nearly 7 months now and the shading looks terrable its reall dark in some places and basicly looks pretty shithouse and makes the awsome design and look of the tribal look bad. now my question is what can i do about it can i get another artist to hit all the shaded areas with white ink to soften the shading then when it heals get the shading done all over again making sure it gets done properly ? would this work at all or does anyone have any ideas i can think about doing it really is a shame about the shading cause i really like the blackwork please can someone give me some ideas jay

anyone??

white wont really work too well. ya can have a artist go over it with water and try to bleed some of it out.or have them try to reshade but the dark areas is going to be there. or real nice affect is go with red as a shade or blue depending on depth of the black shade it may have to be hit more than once. dont loose hope and if ya could e mail me a pic of it i could have a better idea and powow with my master,and see what could be done.
