Hi Picasso , Welcome , The horses left front leg seems to be bent in an un natural way. Perhaps a different texture on the trees,like the foregraound one texture and the background another. If you play with the transparencey , you may be able to get rid of the "Roundness" look on the trees. I like the trunk texture on the right though. Great start, Just keep at it . Hawkfyr
