@Serarel I'm going to write comments here on PSF and on furaffinity. This comic has had a lot of effort put into it, and honestly I love each individual page of this comic!
Thank you for taking time drawing this commission. I really enjoy how you drew this idea they had!
The scenery for the background is a calm, pretty looking day. I like the coloring you gave the grass and the anthill. The snivy herself has coloring that make her stand out from the background around her.
A detail I love that I notice is how you drew her sleeping position. She reminds me of a sleeping snake ^^ If she was long enough I can imagine her tail going in a coiling pose. Snivy's yellow streak along her tail and back is a neat detail to see too. It looks like the ants found a path leading towards her head.
I honestly really, really love seeing WHY the ants decided to go into her nostrils.

It is oddly adorable to me seeing the ants think the nostrils are the opening of an anthill.
Pokemon have had some incredibly appealing starter pokemon to me, and Snivy is in my top 3 favorites out of all of them. I'll totally admit I have personal bias though XD I love snakes IRL and that carries over into me loving them in anime and cartoons. Snivy, servine, and serperior are all really enjoyable designs to me. The way you drew Snivy in this style is amazing to me ^^
Seeing the ants crawl along the walls of her nostril reveal why her nose felt so itchy. I love seeing the tingly sensation lines near her snout, and I really love how the outside view of her nostril shifts from a long thin nostril into a oval shaped itchy flare.
It is not just her nostrils that reveal something is amiss. During her sleep her closed eye and her mouth begin to feel the effect of so many itchy intruders. The face expressions of her building sneeze are great to me

I love the color you gave her open eyes
The three sneezes each grew in urgency as her snout desperately wanted all the intruders to get out. Really nice text you used for the sneezes themselves being different from her normal speech text. Snivy's entire body felt the strength of her final sneeze! She looks so cute being confused at the final panel. She's gotta use either her tail or nearby grass blades to swipe and clear her runny nose.
I loved each part of this comic! ^^ Thank you so much for drawing this commission! How is Tiko? I hope they are doing well!
