I find it very difficult to finish a picture without shading it, and this was definitely a challenge-- even now I'm not sure I accurately give the feeling of overlapping tentacles in this one. Drawing tubular shapes is not something I'm used to, so I'm trying to figure a way to get real-life references for this-- I prefer referencing photos to using other people's work, so I can better define my own style.
Maybe I could build something out of clay to use as a model. Hmm.
If you're reading this, please let me know what you think of this-- I'd really like some concrit.
