It's not a bad start. ^_^ I think what looks wierd is that everything except the render is sharp. -_- I don't think that looks good. I would sharpen up that render and slightly blur the rest. still, not bad.
You can change your stock in a million possible ways. I admit it's hard, since you're beggining, but you can, and I have to agree, it is a little sharp. The render should stick out, so you shouldn't have blured it. It's the other way around. You blur the bg so that the render can stick out. But the effects on the bg are okay. The text is well, too. Keep it up. I say it's okay.
everything but the render is good lol find some good renders and such and you can get some good tags pumping out.
Not bad, the c4ds are a tad sharp, the blur tool can fix that easy. Also work on colors, there are too many right now IMO. Not bad for a start, could be much better IMO. Keep workin at it.
You could: 1) Copy the render layer 2) Sharpen the original render layer 3) Gaussian blur, 2 px, the render copy, and set it to hard light That should make it stand out a little
