This was very enjoyable to do, and I spent time to just go nuts with a lot of the detail. I think these dark tunnel-like "belly of the whale" type spaces haven't gotten a lot of representation in this contest, so I wanted to get in on that, as I think those scenes look very cool.
The original size is 5000 x 6810, but for deviantArt purpose I uploaded a scaled down version. The signature is removable, as well as all of the spiderwebs and a few tiny spiders, they're on their own layers, just in case anyone's arachnophobic.
Also this is my second entry, and the first one can be found here: [link].
NOTE: This is a re-upload because the old one's image file quickly got corrupted. I've deleted the old entry.
