Actually i just started work with textures so i am not good enough on textures.Comments?

looks good a.q

Fine for one of youre first works with textures.

Render work is allright, but looks to blurred. Try to sharpen the render a bit. The b/w thing looks okay. Textures looks fine, but some of them could be closer to the render. You could use some more as well.
The font is fine, but to simple, and could be blended better. Chose a color that fits the background. In this case a darker one.
The logo dosen't blend that well with the rest. Its quit hard to blend a render nicely, so woulden't use it in the start.
Background is fine. Textures looks fine, but the color could be better.

Keep working, take a look in the tutorial section
