I know that feeling all to well :(.

Take your time with this matter, buddy. Maybe taking a little break from making art will help you. ^^

^ This.

Like the dragon says, take a break. It helps.

To paraphrase...

It ain't nothin, you ever said or ever did wrong, your muse done gone.

I've been there myself and am also trying to work through it. I'm getting there, sort of. Occupying yourself with something else might help. Stop focusing on the artwork and focus on either writing or maybe another hobby. Me, I focused on building an RC boat out of scrap. I just need to solder some wires and it shall be ready for her maiden voyage!

*Patpats and hugs*

Maybe instead of looking at other peoples art you should look at your past art?
You really did have a neat style and your art was always pretty well done! Better than anything I could do.

Try working in another medium for a while. I suggest writing.

Write up a story about some characters that you create, and run them through some situation. You can do this entirely in your head at first; it sounds like your imagination is a little starved for attention, and you need to find that hook that will let you picture things more clearly in your head. Come off the drawing pad or tablet for a bit, and get back inside your mind where all this good stuff came from in the first place.

To start, just try to picture some characters of yours doing those things you find interesting. Don't try to force it; if it doesn't feel right in your head, it's not gonna translate to text or imagery well. Be inventive with it. Mix in some humor, some action, some Conan the Barbarian, some Star Wars... whatever strikes your fancy at the moment and feels like it will lead to something more, something you can build on in your mind.

If you find yourself kinda daydreaming about what they do next, or feel like you've got a story going, maybe write some of it down. Then take what you wrote and imagine it as a scene, and draw from that for the actual art. Well, the *imagery*; you've been engaging in the art side of it for a while now if you get this far. ^^

Good luck. I hope you can find an idea to spark something new.

You need some ideas, Kaa?
I have one that you might like.
That is, if you're willing to hear it out.

You are very talented and had put a lot of energy in your work in the past (a very long past). Such a down phase happen to a lot of creative minds in their lives (sometimes it can take years).
