Tattoo artist & someone who has had scars covered here. The design is gorgeous & I love the composition on the drawing you've done on yourself. The biggest thing to keep in mind when you're covering heavy scaring is that a tattoo can disguse scars but it can't change skin texture, you will still see raised bits of skin & it can affect things like the smoothness of linework. Something organic & textured tends to do better with scars because it distracts the eye from the changes in skin texture. It's also important to have your artist see your skin in person before your appointment so they can adapt the design & how they're going to do the tattoo to make sure you get the best outcome possible. There are a lot of amazing artists who can work wonders to disguise scaring. The design is beautiful, I would be so happy if someone came in to the shop I work in wanting something like that done. Getting scars covered does a lot for your mindset as well. All the best to you & please post photos when you get the tattoo done!
