I have been drawing using SAI for a long time and i can't figure out on how to make it nicer.I feel like my lineart is not clean enough and i couldn't identify the shadow coming from the light source properly.Also after i've coloured them it looks perfect for a while until I started to feels like its 2d-ish because of the lineart.Lastly while I draw the lineart I find my lineart really stiff too and I couldn't find a way to Not make it stiff.

Soo how can I improve it or any other way for me to make it make the lineart better.



BTW:I've seen his/her works here :https://www.facebook.com/media/set/?...3634166&type=3 and I want to noe wht did he use to make tht lineart ? o.o
