My CnC may sound harsh:
The background is kinda messed up, I know you're trying to make it like ice and everything but I have no idea what it actually is :S
Also, Keep the render clean and away from effects, also I'd move it to the middle and add some text, lighting, a boarder, And make it blend in a little.
If you read some tutorials, I'm sure you'll improve!
Everyone once started off like you and soon you'll be as great as the other people on here![]()
