I made this out of fun. Wanted to know about skull real structure. I've always happen to draw skulls but never made one with this definition. Plus i gave it some magic blue shit on it that makes it cool... i think.
Well my only advice is ...If you dont have any inspiration dont work and dont force it, watch new movies, try new things and do anything else. Are the small things you will find again inspiration. But as well I hate when it happens, but now Im trying to control myself for not to work and mess up what it is done so far.
I absolutely think the same as you. although sometimes you need to work so you won't get lazy in the meantime. i think that there are always other things to do that will nurture your art in case your lost doing something. you should watch this video on creativity is awesome. [link]
