Great job on the pics!
Adding a thermometer to your kettle will help you hit your strike water temps better. I know this really helped me. I typically shoot for 10 degrees warmer than I want to mash at, usually works like a champ.
As far as refining your process, I would say that only you can do that. The BIGGEST thing that helped me, was to stop making changes and just brew! Like you, when I first started brewing, I made changes or bought new equipment that totally changed each subsequent brew day. Try to brew the same exact way every time. That really helped me start turning out great beers, regularly.
Also, I might add. Don't brew styles that you wouldn't normally buy. I went through a phase about 6 months after I started brewing, where I was determined to brew a different style every time. Big mistake on my part. Why am I wasting my time brewing a Dunkelweizen and Octoberfest when I would never order one when I go out? I only really enjoy Stouts, IPA's, and APA's, mainly. While I'm all for branching out. Stick to brewing styles that YOU really enjoy.
