Nice job man, your shapes are positioned well within the cnavas, i like how you've tied everything together through the center, without having to add larger/bulkier objects. This was cinema4d i presume?
Ah it was very brave of you to do such compositioning. For me personally, I'm ALMOST convinced, however I must say there could have been something a tad stronger to tie the 2 corners together. It's almost there, but not quite!
But ofcourse, needless to say, sweet shapes and colors.
