Hi Mate
Your body can only produce muscle at a certain rate, and if you're gaining back too much fat, you're eating too much and need to cut back on your calories a bit, and slow down the increases.
Most men have the genetic potential to gain around 10-15 lbs of lean mass over a 12 week period. Based on your pics, you would fall neatly into this category if you work hard enough and keep on top of your diet.
