Thanks Razen and to answer your question anywhere between 10mins to 30mins on the newest ones and some of the older ones maybe an hour now I just sit there with the pullshapes tool with the bones folder and just go nuts till I see something "In the clouds" and carve out what I see with the shapes and pressure shapes tool. If I don't see anything I wipe it clean and start over. Thats where a lot of my time goes.
That alchemy stuff is great, and so are those figures, especially for being done without ref. I think you should invest time into doing figures with ref, and dig into more anatomy...it'll really pay off in the long run.
