Shipping is not a thing I tend to indulge in except when the medium leans into it. Then, I like trying to figure out who is the best fit for someone.
Grass/Poison with Fairy... and the other one. That's not terrible coverage unless you ran across a Steel type, that is. Really curious about who the third one was now. I hope it was a Heatmor. As for Roserade's waist, well, I thought they all had big bottoms, but I'm not the one feeding her, so you would know better. I'm sure there's diet Pokemon food out there for Grass types.
The bonus piece seems fine to me. Both have a certain "off" appearance to them that only works because it's not just Roserade with that look. Then again, much of your art seems more like actual paintings than digital and is vastly different from the official style we see in Pokemon media.
Happy late Valentine's Day! ...I got my butt kicked at work trying to cover for all the kitchen duties work during a store audit. The only love I felt was while driving away from that place afterwards. I want to believe your day was more enjoyable.
