I'd be a little more modest if I were you, even if it pains you to do so. The colors Hari-Jizo used to color Omoi, are very tacky, and look like the color of plastic toy balls, but the actual coloring skills between the 2 of you, aren't vastly different. I commend you for trying, and not useing annoying colors, but first off, the lineart in your coloring is kind of sloppy, especially the shape of Kakashi's sharingan. Having a good quality cleaned panel of lineart, will actually help a lot with making your colorings look better in the end, so keep that in mind before you start a coloring. Another thing I noticed, is that the shadows on Kakashi's face look kind of out of place. Since you're at a novice level, you're bound to make some mistakes, so the best thing you can do is, learn from those mistakes when you make them. If you fail to learn from you own mistakes, you might not improve as quickly as you want to, so it's best to be modest in the beginning. Well I hope you know my intentions are good, and that I'm just trying to help you out. Some of what I said may seem a little bit harsh at first, but I'm talking from experience, so please take my criticsm's in a positive manner. If you keep practicing this style of art in a dedicated way, then you'll start to progress for sure.
