Welcome, @sh2b Offhand, I'd say more quality calories per day, and more training per day/week.
For details as to establishing YOUR daily macro needs, and for details on various training programs, stay tuned ... HERE.
Lotsa bodybuilding boards, some are good, but this one has some old fucks who know shit, who've been where you are, done that, and who are old-but-still young enough to remember what you are wondering about.
You look like a guy who doesn’t have much trouble staying lean naturally. You could probably get away with higher calories and staying lean. Just keep in mind quality calories matter. People can argue it all day, but quality and nutrient dense calories do make a difference. Especially at the cellular level your metabolic processes. As said already, you look pretty symmetrical and well balanced, that’s a plus. Maintain that symmetry and balance while adding more weight. Creating an imbalance by adding strength and muscle to certain areas over others is just asking for issues and injury. Also, as [mention]rawdeal [/mention] said, stick around here. This board is a plethora of knowledge and experience to help you reach your goals. Best of luck boss!
