Doing a diorama for your first mini is pretty ambitious, I'm impressed! It's a nice little scene - the pose of the mini fits the action and the positioning of the animals makes them look very attentive to her. The main colours are well chosen. The drybrushing on the critters looks a littleoverdone, you might need to get a little more paint out of the brush or use a lighter hand with more passes. Excellent first work, though!
