Really lovely, great depth and color!

Oh how beautiful! This is like a cross between Peter Max and (Monty Python artist) Terry Gilliam.

Rangoli is a traditional decorative folk art of India which made on floors and the base material is usually dry or wet granulated rice or flour to which sindoor,haldi and other natural colors can be added,even people use colored sand and flowers/petals too.So it is not possible to imply a 3D effect in rangoli as it has been shown in this image.Although it is a good piece of art but far from reality.

Sorry but is not possible to use rice, flour, sand or petals with photoshop :P

Nice work ,but would have been better to make it larger to get a better look at it. gl

@author, I think what @newrays meant was that, smooth gradients & shadows are kinda not in the spirit of rangoli (read: implementable). Steep gradients & shadows however work.
Besides that, nice design, not practical, but nice design & equally good implementation. Good luck

Very Nice Congrats
