The pencil drawing looks exactly like my old drawings from years ago (which is a good thing!). You capture form and depth well with shading. The only thing is that the darker part on Cyndaquil's back is a little messy in terms of shading (some lines are visible and stick out) and should blend more like the other parts of the drawing you did well. And I don't know if it's just the quality of the camera, but it seems like highlights could be brighter in some areas by using an eraser. Highlights add more form to a drawing and make it "pop" more if that makes sense. But other than that, I can really see that you grasp and excel at the concepts of lighting and shading, and I hope you keep practicing and getting better. I commend you!
As for the color drawing: there is little bad to say about it as well! I was always hesitant to start drawing with colored pencils (I'm assuming that yo use colored pencils), but once you practice and practice it isn't so bad. A few tips and things to keep in mind are that to get a color darker for shading, you often need to use different colors. Reading some tutorials on color theory should really help. Pressing harder with the same color works well to an extent, but using a different color aids in making a color look much darker and helps with shading. My go-to colors are purple or a dark blue to darken colors, and a limited amount of black so as to not dull any colors by using it too much. Shading with colors is all about layers, and I find it easiest to work from light to dark by laying down a light, base coat (color even lighter where highlights should be) and gradually layering on darker colors, leaving the lighter areas untouched. It may take a while, but the end result is worth it.
Of course, as you said, everyone has their own way of drawing, but I thought I would part with some of what I've learned through personal experiences to hopefully help you. But keep the good work up! Trial and error will teach you your strengths and weaknesses, and it's always crucial to look at other people's art for examples and to see what style you do best. I look forward to seeing what you can do with more practice!
