MLP Next Gen Character Development

I really need to develop my characters so I'm asking you guys for art prompts. I'll actually upload these sketches this time and there will be dialogue in the desc. XD The only ones I could think of were Thunder preening while Cinnamon is trying to work and she has no idea what she's doing along with Pinny just seeping around with Pandemonoum who she calls Panda. Who knows, I may even include your oc if you give me a good idea.
