: I hope you don't mind, I did a paint over of your piece, I liked the concept, but a few issues were apparant. The paintover is the top image, and your original image is below for comparison.
I boosted the contrast on the beast, and strengthened the forms a little bit. Also a neat little trick is to add some fog to give the piece some atmospheric depth and boost the scale of your creature, it also pushes foreground elements foreward. Sometimes using birds will work as well to show scale, but they looked out of place in this particular image. I also changed a few things in the background to show the creature's silhouette better, and give some better flow. I got rid of the log in front of the creature cuz it flows away from your focal area. While I added a tree branch in the foreground to flow towards your creature, rather than vertically like you had. Finally I added a tiny bit of red to the creature's head and neck, and gave it more of a red eye, red is a very attractive colour, the human eye will usually look for the colour red first above all colours so adding it to your focal areas can help shift the focus to your liking, though be careful when adding it to objects in distance cuz red fades quite quickly in atmosphere.
Ok, now if you squint your eyes you will see how the piece reads more clearly than before. Also see how objects in the image now direct your eye towards focal regions. Once again I hope you don't mind, and hope you found this useful in some way.
