O_o jaggies and randomness. it looks ok, colors are alright, but the render itself isnt anything special. 3d abstract is really dying i think (for good reason). im not trying to be an ass here, im just ranting in general, not at you, dont mind me ive just seen too many of the super random create a torus, array, modifiers, slap some brushing on the top and yay its abstract. lol as for your piece in particular, i think it has good depth and color, but its just too random for my tastes. Try to come up with a completely original/creative idea for an abstract and do that or try modellling an actual object. keep working
