Start out by building a very good strength base. This is done by working in a rep range of 5 reps for relatively high, yet manageable volumes. This is NOT POWERLIFTING






. This is called building a good FOUNDATION. SMALL SKINNY PEOPLE NEED A FOUNDATION TO WORK FROM.
By building this good foundation of strength, you will also put on a significant amount of size. Work towards getting a 400 lb. FULL squat, a 500 lb. deadlift, and a 300 lb. bench press. You don't have to hit those numbers exactly, but spend a few years working towards getting close at least.
Once, you have built that foundation of strength (and the size, which naturally comes along with it). The "hypertrophy" range would then become much more effective. Now, if you do not build that base, and just start right off working in the hypertrophy range, you will not be working as efficiently as possible.
Starting strength is an EXCELLENT routine for building that BASE. Moodster, I'm sorry, but you do not have the base yet. It doesn't matter how long you have been lifting for. Judging by your pics, you can pack on lots of strength and size within about 6 months by following starting strength exactly as designed.
I wrote a long post about this a few months ago, here it is:
