Leopard ACEO in acrylics

I decided to paint another animal aceo.  This one gave me few problems but I kept working on until I was happy with the final painting. 

I am planning on painting a 6 x 8 inch  leopard but haven't decided yet if  I am going to use oils or acrylics - if I paint it in oils then I will have to wait for each layer to dry before working on the next one so at the moment I am leaning towards acrylics.

Leopard measures 2.5 x 3.5 inches and is painted on 300gsm smooth Arches watercolour paper.

Many thanks to ESP for the reference photo.
