I'm 25yrs .I have 6ft tall.but I'm too lean and poor weight... other wise I'm OK.im doing everything proper like others.. my appearance is so bad.. I need some fat.. im hardly eating.. but no improvement in my body... wat can I do?

It just my suggestion.
1st, have a positive and a desire to change your body (YES, YOU CAN, just depend on how you shape it)..
2nd, I don't know what kind thing that you mean doing properly, but was it works your muscle (your entire body)? If not, try to more active (body building would help)
3rd, eat sufficient nutrient, drink more water (not tea, coffee, soda, etc) and rest well

Maybe you will get down sometimes (normal, we are human, aren't we? ) then see for the 1st rule..
