No i'm really bad at texturing :D,
The character woul need more dirt, and metal things with some scratches specularity and dirt also !
for the floors the ones on Follout 3 where you see stones blocks overlapping is really great , and you really think it's models , but it's just texture and normal map on terrain !

I just said that you could make some floors packages also, specially with multitexturing tools, now it's something lot of people perhaps woud like ?

You could have World of Warcraft pack style, or a Follout 3 apocaliptyc style !
