I'm fairly new to Illustrator. I bought a vector graphic of a wolf for this logo I designed (see screenshot with purple on white logo). It looks good when it is quite large, but if I scale down the logo then my wolf doesn't look as good anymore - you can barely see his eye and somehow his fur looks a bit too bulky and out of balance for the image (see a screenshot with t-shirt design).
I was wondering if it is possible to somehow increase the negative space in the wolf graphic without screwing things up, so that the purple (or gold on the t-shirt) becomes thinner leaving more of the negative space. I am concerned about manipulating individual anchors, as I think I'll make it look weird.
Or if you could suggest how to improve on the wolf graphic otherwise so it looks nice and crisp when scaled down - it'd be most appreciated.
