I've been using inkscape to make poster-type things for a while. I'd like to draw people and objects. Does any have a tutorial on how to draw 3-dimensional or otherwise good images of humans? Or any other objects, such as buildings and plants? All I could find was a coffee cup.

A google search should provide you with a lot of tutorials.

Plus, check out the Tricks and Tutorials, as well as Inkscape Resources forums. I haven't seen anything on drawing people, but then I wouldn't be looking for that (human forms are WAY to advanced for me ). In any case, you should find plenty of tutorials from these 2 forums alone.

Good Luck!
