I don't have artist's block anymore. I write down all my ideas so that I always have something to draw. Also, I notice that creativity is something you have to 'work out' like you do - or should do - with your body, the more you create the more creative you become. I had a hard time finding ideas but now they seem to come to me.
My major problem now is lack of motivation - that doesn't count as artist's block, does it? -, I keep procrastinating doing art, I always think that all I have to do is just 'do it' anyway, but I don't know, that have been so hard x.x
