Thanks, Kristen!!
Small spcies, as Ranitomeya, take me from about 1 or 2 hours until it is finished, but I do RTV (silicon) molds, so second ones not need this long time. Medium sized species, as Litoria, takes at least a couple hours. I want to begin with a big project: the Beelzebufo, I think it will take at least 10 hours to sculpt (meybe 15 or 20), a couple hours to mold, another couple to make the resin figure, and 3 or 4 hours to paint. But this is a future project, now I have to start with some tropical birds.

Thanks again, Heather!!
I am working in a website, but I do not have anyone in this moment. What I have is a Facebook profile, as "Gorgonopsia WillifeArt". I have also a pdf catalog , I will try to send you.
