Ideally it would've been preferable to get a professionally done skin fold done in January, but the change in measurements do suggest a desirable body comp change. (i.e. lbm preservation, fat loss)
Calf, forearm, and upper arm measures suggest you've at least maintained skeletal muscle and everything else definitely looks like subcu fat loss. Really nice work, Trex.
I agree that the period of "newbie gains" is likely about finished now, which means it'll become more challenging to effect further desirable body comp change. At this point I'd encourage you to look into finding a qualified person who is trained to use a high quality medical grade skin caliper to establish a sound baseline lbm. Four to six months down the road you'll really love that you did that for yourself.
