It's was my picture for Steemit contest by yellow color devoted.
It was yellow color theme, and I drew a golden lilies.
One of most beautiful yellow flowers of June.
(yes, I draw in Paint Tool SAI now)
In vercion 2 of SAI you can fill an background with gradient.
I copy a background layer & maked it darken to selected shining petals of lilies.
More deep shadows in the center of flowers
Then I wanted to add a shine to edge of petals.
I added a new layer, painted on it yellow in petal contours.
Blurred it with Gaussian blur filter
I replaced this layer under layer with lillies and changed blending mode to Shine
It seemed to me not enough, and I maked a copy blured layer, replace it above the layer with flowers and changed blending mode to Hard Light.
This view is better!
I maked a centre shadow one more darken.
Finally I added a beautiful bokeh behind the flowers (on new layer) and changed blending mode on Linear Light
Some color correction and final sharpen in Photoshop.
Have a nice day!
