Staying inspired when you're a creator can sometimes be hard. For me, I usually get a wave of ideas at a time and then complete nothing. Although when that does happen I do these few things to find that spark again.
No matter what I am striving to create I almost always turn to magazines. I have collected a ton this pass year because there is always something in there for me. There was even a point of time where I was subscribed to monthly vogue and was able to get my hands on all the newest issues. Once that stopped, I would just purchase when inspiration was needed. Another alternative could be Pinterest. I absolutely love opening up that app because no matter what you're looking for you can find what you need in just a few clicks. Create a mood board with the images you see and create around that. The inspiration will reveal itself when you less expect it.
Lastly, watch a movie. You wouldn't imagine how influential older movies are these days. I've seen so many individuals create amazing artwork inspired by films, song or even other artist. Take your time. I hope this sparked something new for you.
Sending love and light.
