The angle is good, and so is the framing of the shot and the subject is in a good position in the overall image.
I would personally work with smaller sizes, and also if you put some kind of border around the picture (even if it's just 1 pixel of black), it helps to separate the image on devART from the background color on devART.

The colors could be better, but that's kind of what happens when forestry and grassland make up a background - green drowns out everything.
I couldn't really express how to make the photo look better in an aesthetic way - I would suggest browsing popular photography on devART to get a better idea of things you can do to make your photos look better, in terms of angles and positioning and cropping and whatnot.
