TAST - cross stitch

Task for TAST for this week: cross stitch. It seemed to me common and trivial, so I add some more different stitches. On first picture I started with red cross stitches in three dimensiones. Then I made some green and black stitches to make central composition.
Second piece: only one cross stitch in the centre.
Third one: I started with red, again only several cross stitches.
I used cross stitch many times before TAST, you can see my older works below. I especially love the last one, it looks like patchwokr, but it is cross stitch on whole surface of fabric.
