Zentangle Challenge #123 - Is it a Zentangle?

This is my response for this week's guest challenge at www.iamthedivaczt.blogspot.com. Hummmpfff.... I like "pretty", and that's not what this is. This was a real challenge for me because I haven't set out to create new tangles - I'm much more comfortable with working with what already exists. However, as you all know, once you start working with patterns or tangles, you see them everywhere and it's hard not to try to deconstruct a pattern. Thanks to CZT Maria Vennekens (and Laura), for again nudging me out of my comfort zone and encouraging me to stretch. These are all individual patterns that I've named, though I'm not at all sure they qualify as tangles or if they already exist somewhere. The stacked squares is something I've "doodled" as long as I can remember; the rest are based on patterns I've seen in various textiles. I called the flowery squares (from a wild Caribbean skirt) 'Matis because they remind me of my double clematis, and Jester was from a fabulous coat pattern I saw on the subway one day - very dynamic. Stickles is a tiny band pattern on one of my husbands shirts. Shielded is part of a pattern I saw on a chair in a store window. (I have worked out step-outs for all of these except Stax.)
