First of all this is an amazing digital piece! I have not done a lot of Digital works of art but I know it requires hard work, patience and determination. The first thing I like about this wallpaper is the star dust in the background around the earth. It makes the planet stand out more from the space around it and gives it more depth. Another thing that I like about this piece is the shooting star because it fades in from the star dust which gives it a blurred effect which I love. The finial thing I like is the shading and how much of a phenomenal job you did with it. Overall keep up the awesome work!
