my next tattoo im planning on doing an angel on my back, at first i was gonna do my ribs with one of my planned tats but i dont think im ready to get it dont on my ribs yet ;P

im planning on getting this:

but with a little more detail on the wings like this:

i was wondering if i should just do a background with it also? and if the detail of each feather would be good or should i just leave it as the original drawing? and if there could be a better spot for the tat, where should i have it?
