The character here looks more felid than canid. Its paws seem kinda big (like a lion's) and you draw it without a chest. Moreover, I'm not sure a dog's back can bend like that. However, I'm sure a cat's can. Also its eyes are too big and round to be a gods eyes. Dogs eyes are smaller and more almond shaped.
Wow, absolutely beatiful. Idk if I'm looking too deep into the picture, but the hints of red inb the light blue really show the expression on her face-- a lot of peace and innocence, but a hint of danger and hurt. Still, not enough to take her down. They also look like maybe lights from cars, and the fence together look like a sign of rebellion. (with a good cause of course) Stumbling across this dog would give me goosebumps and my heart would skip a beat. Very intense.
In that case the problem is that your image is in Adobe RGB color-space, instead of sRGB color-space. It is not a per-computer issue, the issue is that most browsers do not support Adobe RGB and think that the image is in sRGB. I know Firefox respects this, not sure about any others. You can change this setting before you save, or even before you start, and it will have no effect on your image's intended colors. The main reason to use Adobe RGB is if you are going to manipulate the colors later, but for digital painting sRGB works the same.
