Hi guys, im looking for opinions and ideas on what i could do with this tattoo to expand it to a half sleeve. i want to keep it Japanese themed

this is the tattoo, i need to go back and get the sun’s rays sorted as they aren’t all the same size and a couple are not tapered like the rest. also the red needs doing again imo

my ideas were to have a Foo dog on the front of my bicep with more water around the Koi then somehow fading it into foliage round the Foo dog

i like this Foo dog so was thinking something like this but im not sure if it would work or not

all opinions and thoughts will be greatly received

cheers
