Very nice work
A very bold, "FIERY COLOR" scheme that adds to the ferociousness of the tone. The sketchy line work matches the usual tone of freedom that is associated with birds. It also creates a look of realism in spite of the line work being rather dark and thick. A white backdrop spotlights the "SATURATION OF COLOR", as well as the beauty of the entire piece.
~~THINGS TO IMPROVE ON~~
Some type of frame and or border would really work nice with this even an orange border would accent the bird more.
