I'm not into He-man at all and I probably wouldn't watch the original show but I've just seen this in a youtube video with an instrumental version of the He-man theme and I absolutely love it. If the show looked like this...wow! It looks awesome, the lighting is perfect and I especially love how Battlecat(?) looks.
This is absolutely amazing! So much nostalgia! :') It would totally make my day if you ever made a similar one with She-Ra on her horse to use as a desktop wall like this one! Keep it up!
You know, I actually at first though this was a teaser painting for concept art from a movie... it is just that professionally rendered. Like all of your MOTU art, it is a nicely done take on something truly iconic!
