What can I do to improve my physique, male model like?

I am 21 years old 5'9, avg 143 lbs. I have worked out before and bulked up but I noticed It did not suit my asian frame that well. My plan now is be lean, and very defined and somewhat bulky in the right places (if you know what I mean). - muscles should make me look taller instead of stockier. Also I have access to gym, creatine, protein supplements and post-workout supplement. But as of now I do not have the time. How about a home program using one barbell?

to be honest the best way is not to go on a diet as ive tried them all and diet pills and they dont work lol but just change your diet and go swimming 4-5 times a week for about an hour each time it tones your tummy and all your body up wonderful too ! i lost 2 1/2 stone since may its great and i eat loads too im just eating the right foods but instead of swimming try aqua arobics its great and really fun ! great question goodluck !
