Looking very good Jan. I like the addition of the closed buds. Some translucence would really make the blooms and stalks stand out. I think that Tulips generally have a more waxy almost plastic look to their specular.
thanks for all the comment guys i will make a new topic about roses because i am a little frustrated-:) i would make a bacarra roses but that,s a heavy job to do. maybe we can do it together to learn something i will make a start about the plastic/waxy feel i use xfrog stand alone and artlantis for rendering i will ask a hot shot to make a render off it i am not the best render man-:) but i have a lot off fun making all that nature-:) jan
