To make it more readable you're going to have to thicken the lines in the fur, as the smaller widths will get covered by other fur. That being said, design #2 would be the easiest to see, although if you were to make the width of the other designs larger you might be able to get away with them.

The lines have been thickened substantially from the original design and I only have about a 4-5 inch diameter circle to work in for this central design so unfortunately i dont think i can thicken them much more without it becoming just a black blob in the middle, which in the end, it might come down to just having a solid center.

I do agree design 2 would be the easiest to read. So it may come down to that as the final choice.

Thanks for the input ^^

I would suggest #3 Since it doesn't look to simplistic nor entirely to difficult brush on compared to the original design. Why i didn't say number #5 is also because The completed circle makes it look more wholesome and completed. The crescent space may look like it has some spiritual aspect.... Like Diana! xD With 4-5 inches of working room it seems like you wouldn't have to make the lines to thin to put all the detail of it in. You could try to practise the designs on small patches of fur or on some other medium.
