Sure!, this one was made very long ago, however, i can tell you about the process for sure!



First!, this piece sparked from my passion towards pokemon!, so i tried to imagine the Pokemon battle from Pikachus perspective, > how it feels to be so small against a giant Charizard but still knowing that you have your own skill and your own chances to survive, so basically



1-Visualize the scene on your mind, if you can, project yourself as one of the characters and visualize it from his/her/its perspective (like in your mind navigate on an actual 3d scene)!. then become the character!.. Freeze the moment (like stop the video on your mind) and make quick notes about it (small thumbnails! (really quick and loose ones ) so you can decide for the best composition



2-Make sure to play AWESOME EPIC music!, usually related to the subject, on my case i was listening all the pokemon remixes I found! the ones that really made me feel epic!



3-paint! keep refining, testing, show it so you can get feedback! and most important



ENJOY the process!



do not hesitate to ask more question I will be happy to answer!
