This texture pack looks gorgeous and I look forward to using it sometime soon, along with others you release!
I would like to give a suggestion for your work for maybe a secondary place of income, or two. I think your texture work is so lovely that it may work beautifully on a site like makeplayingcards dot com, where you can submit designs to place on the back of cards for people to buy, and your textures would be super fun on a deck, maybe with a little extra work.
Vida studio is also a nice place that favors patterns for design submissions for their products, and while they are expensive, they could enjoy your work on some of their products too I think.
Cafepress meanwhile has tons of products, and some would work particularly well such as notebooks, shower curtains (The blue tilework would work nicely with a shower curtain I feel in example), and the picture frame.
I could go on as there are other sites that would like your work, but those three in particular come to mind.
