Thanks! :)
After the brainstorm session, the 3D artist started modeling the dog using 3DS max. He used previous images from other games that we made as references for the 3D model.
At the same time I drew fast concept arts using photoshop just to explain to everyone on the team what the game should feel and play, with UI and player sizes, some colors and effects.
The final thing before implementing the arts onto the game was to create the textures to put on the 3D model. That was done by the 3D artist using Affinity, who also placed the camera on the 3D space to render the character in all animation frames (run, jump, idle and dash) and the platforms.
We used Unity2018 to create the project, so we imported the assets and edited the final bits in there. Unfortunately we didn't had time to add the chatacter's final animations until the deadline, but we have a newer version (Android included) ready to be posted as soon as the rating period ends.
If you have any more questions, please feel free to ask! Thanks for being interested!
