there is one of my work.
It wasn’t to hard for the modeling but I am struggling with the texturing.
especially in the background so if anyone could give me some advice it would be nice. 
This is the second one
that looks pretty cool 
the face looks like its not quite on the can though…
what are you trying to do with the background?
I am trying to make the background look more realistic but i am not very good in texturing.I tryed to make the wall and the ground dirty but it didn’t work well.
Im still a noob actually, but I believe you can create a bump map which you could use to give depth to the cracks on the floor…that would improve it somewhat. I think there is a tutorial on www.blender3d.org for that.
For the wall…how about adding a rocky background…
create some textured rocks and have them filling up the background a bit to add that little extra. This could also hide where the ground meets the wall…
just a suggestion
Hello again.
Thank you for you help “code_astro”.
I have changed the place where the wall meet the ground and I have added some stuff to hid a bit the back.
I wasn’t able to make a better texture but i modified it a bit.
(It Is the same as the second one in the top. Don’t try to find the difference)
