The outside looks much better (and safer). However the ground wire from the meter base should have been inside 1/2 inch conduit to protect it from physical damage (I'd leave it alone now though, not that big a deal).
The conduit to the shop is not vertical (or maybe it is the angle of the picture ). Not technically a problem, but it would annoy me.
I think you should have gone with a 30 slot panel. I realize you are somewhat limited by the size of the hole that was already there, but if there was room below I'd have gone bigger while you had the opportunity. You will have little expansion room left once you tie in all your new circuits unless the plan is to pull out all the old ungrounded cables.
Most of your existing wiring is ungrounded. If you are not replacing the wire for those circuits the outlets connected to those them the should: A) Be the ungrounded type. B) Be a GFI, or C) Be protected by a GFI.
All insulation from the NMB wires should be removed to within 1/2 inch of the top of the inside of the panel once they are connected. I see a white cable - 10 gauge I think - on the left side with insulation on it, but maybe that is the dryer circuit you plan on pulling out anyway.
Overall it looks like a decent job. Thanks for the update.
