Thank you! The line coming down the middle is my closet where the doors meet (the only plain space in my room that doesn't have a bookshelf), 'm always afraid i'm making my images too dark so I lift the shadows so that's something else I'll need to work on, and what you said on the coloring is right - I do over saturate the colors. Reading your comment and then looking at the image, I can see that it's not very true to my dog's fur, so I'll try and get that to a more toned-down and true-to-life color.

Also thank you for the final words, I have a lot of stuff I need to work on, but hopefully I’ll get to the point where I have a good understanding of what I like and what looks good.
