I'm glad you like it. My general philosophy is to increase the amount of information the game provides you visually, wherever I can. I'll be uploading it to DFFD in the next few days, which should resolve any download speed issues some people are having. My web host should be pretty fast (they're one of the best), but a little redundancy never hurt anyone.
I'm using a modified version of Sphr's graphics set (actually I started based on his WIP set, so if anyone knows of any issues there please let me know). I haven't expanded the races yet, although I am working on making his gobbos grey in order to fit canon. I made graphics for the birds only to discover that vermin don't have graphics support yet.
The only new original graphics I've added are a real sprite for the Longnose Gar and Carp (the horror), also I replaced the Tiger sprite with my own. All of the big cats looked basically identical, and I am trying to replace each one with at least a slightly different pose. Based on that Tiger I also converted the Tiger Men.
I also changed all animal graphics so that living animals face left and undead animals face right. It was too hard to distinguish living from zombies in a lot of cases. I added a little up arrow icon to the giant versions of the big cats. That's not really a detail you want to be unaware of, in my opinion.
Funny story, I based the Carp sprite off of Silver Carp based on the fact that I found an article saying they are dangerous to fisherman. Apparently, the 70-80 lb fish are known to leap out of the water when spooked by engine noise. They jump high enough that they can nail a fisherman standing on the boat. Seems DF emulates reality better than we thought.
