Hi Kostas,
I like this effect, similar to your other one...the colors and details are very nice. Would include the outer edges of the flower on the top and on the left...the feel is great...keep them coming...:D:cool:
I like how you liquify the same image for the effect. To make this even better you should try to go for a smooth transition between the actual flower and the liquify effect.
This is neat Kostas, would have been neat to liquify the stem in to the rest of the image to blend it in more. Would be a good candidate for OOTB. (Out of the Box)
