Hey there glad you found it helpful, I just popped over and checked out the introduction post - there are only two aesthetic suggestions I have and they really aren't big.
First is break up your paragraphs into smaller ones, it just makes it a bit easier for the reader to track where they are - as I said minor.
The second is to center your images, that way the layout has a nice even flow and your eyes aren't forced to the left with every image - again not a big deal but when you create a smooth flow it makes reading easier and it just looks nicer as you scroll.
Anyways hope this helps, otherwise the post was great - good luck with everything :D
