Lens flares are horrible shitifiers
This might be a good drawing, but it's way too small, and there's a giant, ugly, stupid lens flare and Photoshop lighting effect thrown on top. The lens flare is an effect notoriously associated with amateur Photoshop users, and it always looks bad, especially to anyone with a deep knowledge of the program. Lighting effects CAN be used well, but again, they are usually a tell tale sign of somebody who's new to Photoshop and just discovered it in the Filters menu. There's also a clouds effect in the background, and a ripple effect for the water; again, really tacky. You don't need all this crap, let your work speak for itself. It looks like there might be some cool stuff going on with that green flame, but again, it's too small to really make out anything in the drawing. It's impossible to judge the drawing at such a small size and with so many tacky Photoshop effects covering it up.
I wouldn't worry about copyright issues for a couple of reasons, one being that you already made explicit copyright agreements when you uploaded it; another, that you can bump up the size a lot higher than this and still make it unable to print at any decent quality; but most of all, I doubt anybody is dying to steal this for a magazine layout or anything, considering the quality of the work.
Overall, I'd say it looks really amateur, and I wouldn't classify it as Fine Art.
Please, this goes out to anybody reading this who is thinking of submitting artwork, PLEASE familiarize yourself with the definition of FINE ART.
And please don't use lens flares. Thanks :3
