Animation wise, i would've given this a whole 6/5, no questions asked, you guys really went all out. but man, i did not like how the main characters were handled, i think i get what you were trying to go for, sort of a starbarians kinda thing where the setting of the story kind of allows the main characters to get away with there blatant cruelty and said blatant cruelty can be hilarious, but in this case it was a bit hard to enjoy, mostly because the other characters that were being attacked are just too innocent, they didn't deserve the things that happened to them so there was no form of humor to be found in it, it honestly would have been better if it ended on the goblin kid beating them up and throwing them out of the village, giving them what they deserved, and maybe have this be the main focus of the story:

elvis and dimmi attack innocent people trying to get rich and famous and they're defeated justly and maybe even develop as characters to the point where they're not so bad and start winning, with there goals of fame and fortune still intact. i know it's probably not the kind of style the show was trying to go for but i still think that it's one of the only ways it's be good, story wise

overall, i really think this had potential if you want to make it a whole series but the improvement on the main characters is much to be desired, but again, animation wise it's ultimately flawless XD i seriously can't get over it
