idk if I should just post this kind of stuff only in the furry thread but unless you guys say to I'll post it here too
a thing that I'd kinda wanna nip in the bud is that you tend to draw snouts and the like, for lack of a better word, flat
might be a lack of shading or something, i dunno. but what I can tell ya is this:
i'll use this exotic and endangered earless hairless canine as an example:

in a brief, just imagine the snout (and anything else in your drawings, for that matter) as a 3d object and you'll find it adds a layer of depth to the picture. now obviously not the best example, no animal out there has a snout that's that boxy, but it's the same general idea- draw a box or something similar like a wedge or cone, and then add in all the other details based off that simple object. i'd also make the lips a little bit longer, because with how short you draw em it looks a tad awkward. hope I didn't come across as too harsh
or as a hypocritethis video explains the concept far better than I can at the moment:
