fallout 3

First one. Don't like the blur on the second one.

i like the creative text and all but it seems you just added light over an image, not much look going on

Why do I see lots of sigs with the House style text?

You know the square around the first letter. Anyways, what was said before. Personally to me it just looks like a stock and brushes, but it's nice .

This seems like a good comment to start from.
I see you tried creating a flow with the brushes, but the flow with the gun and stuff is pointing upwards so you might want to follow that as a genearl rule.
The green brushes don't fit true, try incorporating more effects, C4D's are really helpful.

Thanks i am still newbie :S
