Alright, Ima give you feedback on your drawings. For one, it's super awesome that you draw a lot and post them on the forums. Keep at it! Though the issue I see in a lot of your drawings is presentation. They're drawn on notebook paper. You can doodle stuff on it for sure, but I recommend getting yourself a sketchbook if you want to use anything but pencil stuff. Give the drawings the respect that it deserves where the paper can actually work with the drawings and material, not distract it. When I see lined paper, I just assume it's not for drawing, but for writing. Another point in terms of presentation is the lighting and angle where you're taking the picture. Ideally you'd want to scan so that it'll be flat, but if you don't have access to it, at least make sure you take it straight above the drawing so that it won't be distorted. The lighting also makes a big difference in how the drawing is viewed. Make sure there's plenty of light when you're taking the picture or bring a desk lamp over. Like I said before, give the drawings the respect that it deserves. For the drawing, the coloring actually goes over the lines and makes it not as clear. So I'd recommend after doing a pencil sketch, add the color first, and ink the lines later. For the application of color, you colored the pink in actually really well considering you're using such a blunt tool (staying within the lines, filling it out completely, looking like what you intended). Though because the pink is colored in really well, the rest look sloppy in comparison (not as filled in, going over the lines that the lineart almost disappears). If you can color in the pink that well, I know you can do it better for other parts of the drawing as well. From the drawings I've seen, I get the sense that you're interested in character design. You can try focusing on the character design first and move onto the background later. There's a lot you can do and learn from just character designing so it could be helpful to tackle smaller goals than to finish an entire illustration with a character + the background. These are it for now, I've said a lot already, but I'll look forward to seeing more drawings from you.
