So, i love all the details you did, it looks qute cool!
The difference to the grass are the trees, they havn´t got so much detail. But I think that your mixture from details and no details is well done. The colours you use are pretty together. One thing is jumping into your eye, the pink antler. i just love the whole picture, it´s quite intresting to watch and watch again.

So, i hope it was an okay Critique, it´s my first and sorry for my bad english, I know it isn´t the best. But keep your work going on!
