hey mate....
if you are going for the mens health cover model look then you are not THAT far off it.... from what I have seen their models vary quite greatly in how much muscle they carry... with a good photographer and a bit of a cut you would probably have the look some of them have....
otherwise... adding about a stone of muscle would make you a shoe in i reckon
you mention only being able to go to the gym for an hour and half well that is too much time anyway mate so assuming a bit of a drive, 45 mins training then back that is plenty enough time. if you are in there for more than an hour you are doing something wrong, maybe others will disagree thats just my humble opinion
but in all honesty mate you look good in the photos, from some of your posts you sound a little unsure of your own ability maybe i am reading too much into it but believe in yourself dude
also mate i have a daughter she is 7 months old and beautiful its the best thing ever aint it!! unfortunatly i dont see her during the week due to work and i often have to go away for a month or two so i miss her greatly
