hey thanks guys!
@Braga.3D: it was just plain sculpt. long process, but definitely worth it. could not have gotten a similar result using alphas.
@SwampGhost: thanks a lot for your kind works. I really appreciate it. I made the wings with zsphere retopology. pretty straightforward. If I have some time this week, I can make a quick video showing the process, if you like.
here is a turntable from the sea dragon. somehow the quality got a bit lost. I'm still new to vimeo... I'll figure it out at some point
