As has been mentioned it does look a little toony, but overall it's a nice chop
Now, me saying "it's toony" doesn't really help, so here are some pointers:
->Look at the base, you'll notice that the brighter areas are infact almost white inplaces, so you need to make these areas a lot brighter on your brushing, and add some of the pink hues from the sky
->The whole paint job needs a bit more contrast i think
->Try and include as much detail as possible, this is the biggest thing to improve realism. You'll notice on the base, lots of tiny variations in colour, mainly in the sky area, yours looks a little more like a block colour
But overall, not a bad effort at all - keep it up
