That is wicked cool; the amount of detail in each ring of the lineart is nuts, and I like how each ring pattern is different. The waviness of the whole thing almost makes it seem like it's moving and flowing.
I find the Cape Breton background to be somewhat distracting from the lineart, and don't really like how it obscures some of the fine details of the ring patterns, but I do like some of the color variation it adds... I just feel like it's too prominent. It looks like you modified the colors of the background image and then laid the partially-transparent lineart over it; I think I would prefer to see the lineart remaining opaque with some sort of color effect applied to it, such as combining the lineart's colors with the colors of another image through addition, subtraction, etc. But that's just me.
Everything is very nice-looking nonetheless; great work!
Personally I don't mind the tree blocking out the patterns on that one part of the image, as you can still see the details of those particular patterns somewhere else on the image. But I do see what you mean by it being too prominent. It is however, what I chose after tweaking it multiple times from either being too subtle or too prominent.
Thank you for the feedback and the generous scoring. I very much appreciate it.
