Nice photo - your girls look really happy too. Its interesting you had a go with the softboxes. I wondered myself, but I don't have enough strip boxes. I like the bigger working space you show they give - the gap in the middle of them. When I have seen Peter Hurley on other youtube videos, he had a much bigger working gap than he did in the demo I recommended.
Hurley used to use Kinoflos before "own branding" but the price of those is even worse I suspect as they are used in the movie and TV industry for set lighting.
Lots of Hurleys stuff has the triangles in the eyes, It makes the eyes very bright and lively looking and he likes lots of colour to show.
People argue til the cows come home about catchlights. I dont think there is a right or wrong as what appeals is so very personal to an individuals own taste.
Your results have encoraged me to have a go when I have enough kit.
