The heavy shading on the sides, with the center lighter makes the "Welcome" hard to read, and is somewhat contrary to the fact that generally, mats are dirtier in the center from foot traffic. Your light source is not clearly defined, as it looks like it is coming from the lower left, when logic would dictate it should be from the upper right, as a porch light.
The "dirt" is too light, and looks like dandruff.

The textures are beautiful, and the rendering itself is quite good. It is just a few visual inconsistencies that are impeding you.

Thanks for the detailed response MossyB. I don't agree with everything you said, for example the center is usually lighter because it is more worn and frayed. However I will take into consideration some of your points and make some changes. Thank You.

I love the texture and the panels on the door. Great work. I agree that the lighting is a bit weird, it almost looks as if the mat is glowing, but all-in-all it's not too bad imo.

p.s. - I'm not a big fan of the wall geometry going through each other. It would be nice if it were the inside of a cube, rather than 3 planes that intersect.

Amazing, nice work with textures, good luck!

Secretsather, the new entry also is now a cube rather than 3 planes.

I preffer the textures the white door and the original mat but the floor and the wall looks more reallistic in the new entry. Both are great.
