No effort.
Sorry, but I can't say it was good or bad. I wouldn't even call that art really.
Looks like you just rushed it and think it would be good as an art submission, but it isn't. Not at all.
Now, about the scene itself. It's OK, but that isn't saying much at all. I can't really say whether or not I should hate it, but I'm starting to see that your art isn't worth looking at anymore.
Practice more and submit art that you think should be more suitable so we can actually review it in more detail.
This is a fine example of poor art, or just a lazy excuse to submit art.
