I have to say that you have worked quite fast! On your last layout, one suggestion I would give is to move the ribbon a little further down AND place it on top of the letter L. It seems illogical to put a letter on top of a folded ribbon like that.
To your next question, there is no Basic Course 2. I had plans for it (for years) but I have not done it. 🙁
Now, if you want more tutorials, there is TheLab, which offers 3 tutorials per month ($10/month) or the DIAMOND membership ($25/month) which grants you access to 300+ tutorials to create individual elements/effects (not complete layouts, but the elements themselves) and 100+ full-length classes. You can read all about those here.
Of course, you can also choose individual courses to purchase on this page if you prefer.
