Well after 10 hours with no reply I think you at least derserve one!..::laughs::
Personally, I dont care for the wallpaper, but, that has nothing to do with the quality of it, it has quite a bit of depth and is very obvious you spent some time on it. I just dont know if someone would want perhaps a "Mirror Image" of their personal "Office Reality" LoL!
My advice as to whether you should pursue refining it, I really cant say, there may be alot of people that really like it if it is offered with perhaps the right theme/WB/desktopX ..etc..etc..
Anyway, theres my "2bits" about it,
prolly not worth much but at least it is honest.
Take care,
Zero.
