Acrylic & Oil Portrait in The Works

I've done my first acrylic painting (it's the flowers and hummingbird picture somewhere on this blog), and found it hard to get nice blends.  Other painters I know said you can paint over acrylic with oils, (but you can't go acrylic over oils!). This is my first painting where I struck it in with acrylics and then ended doing a finish in oils.

I'm liking the speed I could do the blocking in and most of the detail.  It's nice to know I can always jump in with oils over the top and will probably work this way from now on. There's more to do but I  think this is promising.
