bg needs more work, and i don't like the grainy effect on it or the white brushes with red outer glow.. colors could be a bit better, bg is too monotone.. add some simple but nice text in there, tone down the brushing that makes the light at the bottom of the render, and work on the render blending

render effects could be a bit better, and get rid of the white outer glow on it

just keep practicing and have a look at our tutorials and you'll improve
