Opinions by tattoo fans?

I have a tattoo already its a dove holding a banner that says family with a bunch of clouds taking up about half the outside of my right arm... i wanted to finish it as a half sleeve all the way around the half sleeve will have all clouds as filler so its like a sky based tattoo (as some people use spider webs or waves) im also doing a full sleeve on my left arm... would you think its okay to have both sky based tattoos?
