Been missing out on a few, so I'll comment on each one
Mo: B'awww this one's adorable! Giant eye makes me feel it's a baby Mo
For the next two, can I just say you're absolutely amazing at making backgrounds? They are so lively. I'm very much in awe at how much patience you must have to get these backgrounds so detailed and smooth. What kind of pencils do you use (sorry if this has already been asked)?
Kendra and Chase: Your OCs look really nice! I don't spend any time in the fanfiction section of the forum, so it is nice to be introduced to new characters this way. The lighting from the moon is very well done. I love how soft this piece feels, everything just looks smooth to the touch. Footprints in the sand, shadows... You nailed everything!
Chase and Chomper: Gahhh the background! Love it so much

Again the lighting is superb and the characters have a lot of personality to them.
All of these make me feel very inspired and I honestly can't wait to see what you'll have in store for us next. I really hope you'll feel like joining our fanart prompts too at some point. It would be great to get more submissions!
