Wow, that’s a nice design.
I think it does go really well with the roots you’re trying to show. Only thing is, I think it might look better if each image was clearly defined, instead of fading into each other where they meet. One on top of the other.
I’d also, when you get it, make sure you go to someone who’s good at doing more realistic tattoo’s, I think this might look a bit cheaper if it were bold and tilting towards cartoony. Instead keep all the shading and lines inside the two objects.
You might also think about what it’d look like just classical black and skin? I know a lot of people will say that color is better but some tattoo’s end up just looking more classy without it.
But that’s just my vision of it. Neat idea, hope you have fun with it!

Hi

Will make a great tattoo but if you are going to mesh them you need a portrait artist who can handle a lot of fine detail and shading.

Alternatively you could get them separate but slightly tilted towards one another and maybe a family motto beneath?

Just tossing ideas in there.

I agree that the two symbols should be overlapping instead of fading into each other, and I like the idea of offsetting them a little bit (like making the leaf a little higher or a little lower). It might be nice if you added some kind of swirls or vines or something to surround the symbols.
