In fact, I wasn't even able to find anything with just the relief. I wound up having to do some manipulation of several layers in Photoshop in order to get the relief to pop out. But I needed a relief-only layer as one of the top-most layers in my photoshop file, since I had done so much editing, recoloring and outright painting over the layers below it.
I had tried several approaches before going the all-raster route, but was repeatedly stonewalled by technical issues along the way. When working with DEM data I found it either far too low in resolution for the scale I wanted to depict, or when the resolution was high enough, it was impossible to stitch so many small regions together into a single seamless image. The raster data I had wasn't of much use, unfortunately, as it wasn't accurate enough to generate heightmaps that could generate realistic relief. I had two images to choose from, but one was a sliced-elevation map, which produced nothing but huge terraces. The other one I had at first seemed very promising but I soon discovered the image had been unusually dithered, resulting in an annoying layer of relief 'static' across the entire image I wasn't able to get rid of. Very frustrating. For a while, I even flirted with the idea of doing the map rendered in 3D since the elevation was still smooth enough (attached is a 'quick' early draft I did, exploring to see if the idea was feasible). I'm still looking at that as a possibility somewhere down the road if I can work out some of the kinks in the process.
File size limitations also became an issue, as they quickly ballooned up into something that neither my computer nor the programs I was using could handle, which is why the project got put on the back burner for a while. But last summer I got a new computer and this past spring expanded the ram in it and it's tearing through stuff my old computer would choke on before.
