The compositions and texture work in these are absolutely incredible! I think my favorites are 1-3 (such cool pop-artish stylization!), 4 (love the contrast and the way you used that numbers texture), 5 (this could be a large sized artwork, it's so interesting and so beautifully done), 8 (COLORS!), 10 (gorgeous use of texture - if that is texture - and colors, love the grunge-y feel of it), 11 (lol), 13 (I adore the bold color scheme and the composition), 17 (very cool and conceptual use of this texture with tangled threads!), 18 (again, color and texture, ahh *_*), and 21-22 (stunning colors and stylization ♥).
I'm saving quite a few, thank you for sharing! :)
