Ok, first of all, this is a very eye catching piece. Nice shapes, amazing colour effects, and symmetrical. Everything about this is awesome, the style and touches of colour and everything, I can make out the fact that you actually put hard work into this piece, and it didn't take you less than an hour. It's good quality, and clear, however with the same patterns stretched across this work, it makes it look kinda plain. I would recommend that next time you could include some different pattern in the middle, just a thought though! it's my opinion, but it's still awesome!!
Is it bad I saw the comment of asking how many triangles are in this image and I Actually did stare at it for a bit wondering if I could count them? Green is by far one of my favorite colors and this is just amazing.
