Maybe the pupil of the eyes can be alittle smaller.

I like your arts they way they are bro, but then again stick figures would be better then what I can draw so umm ya don't pay any mind to me

The only thing I can suggest is look at other artists works or watch their streams and see how they do it, as well as practicing as much as you can, eventually yer are will look how you want it.

Also yer art aint low quality, trust me on that.

Your arms are slightly out of proportion to the torso. (i.e the arms are a bit too thin)

There isn't enough signs of fur (normally adding some fur on the ears helps this)

Isn't enough detail on the hair

Nappies/diapers/pull-ups: Middle main bit (the absorbing bit) needs to be a bit bigger, the tapes need to be a bit smaller.

Hope I helped and I hope you improve! :)

The only thing I would also like to say is: don't be afraid to experiment (try new things). You never know, it might be a breakthrough!
