I have actually used Eye Candy's Glass filter to make blood, and with some tinkering, it can look pretty good. Set the color to red with a very light reflection and position the light so it doesn't bevel the edges too strongly (be sure to lower the bevel too, or it will look very strange). :) You can see a small example of this method in my image "The Serpent Slayer" (search for Snowsultan in the gallery). I hope that's of some help at least. ;) Good luck with your image, it does look like you're off to a good start! Take care. SnowS Hoping his pictures are worth 1001 words.
