I think you've answered your own question - the growth seems healthy and everything turned up by the next day - so you've done a really good job! Some support, as you sensed, is needed for the greater angles and I like the idea
@gottagrowsometime has of garden stakes to further support - but if everything is looking good, then I don't see why you need do anything further. It's all a grand learning curve and next time you'll know just how far you want to take it and not risk disaster!
Good job!
