A great start indeed.
I would make sure that when you get melt or yellowing leaves etc you snip them asap, they are only a waste to the plant. Also it looks like you've placed green cabomba (think that's the name) in front of you left rock. This plant as you already know is a menace for fast growth. I would move it to the back somewhere as it will, before long, shadow that rock and reach the top of the tank. Just my 2C
Also don't worry about the slowness of comments. This journal should be for you to record your progress and share with everyone, even if they don't reply. Many people just read (I know I do) but feel they have no input or opinion worth while. You're doing a great job!
