This is rose flower. This is one of my favorites. I did this in Poster colors. You can try it in Acrylics too. I have used different shades of Pink by mixing Red and White. To make a darker shade of pink I add little bit of more red than white and to make a lighter shade I add more white than red. And to fill in the darkest of areas I mixed very little amount black with red to make Maroon. To make the leaves I used three shades of green than is light green, Leaf green( Light green mixed with dark green) then dark green at the bottom of the leaf. Then for the final touch I added black to make the flower look bright in dark background. And it goes very nicely with red.
