TLDR: The logo is a little busy.
Personal preference here but....
Stick to one font. The "King" font contrasts wildly with the other font because there's so much embellishment on it. It matches the overall cartoon aesthetic of the rest of the logo but not the other font. If I'm honest, when I first looked at the logo my brain went "shitty mobile game." Sorry.
You're kind of doing the "ye olde medieval font" backwards. For example, why is the G emphasized in King? If you're going for ye olde medieval text (as you clearly are judging by Under The and Mountain, where you correctly capitalize the first letter of the word so it gets that illuminated text look) then how you've done "KinG" confuses it. KinG is the most central part of the image, that's clear and understandable. But I feel like how it's done detracts from the rest of the image and text. It's very cartoony and kind of overdesigned. Why is it red? It's a decent color contrast for the image but the visual message it's sending is murky. Is that supposed to be a gemstone of some sort, going by the cut, chipped and beveled edges on it? Why is there iron work around the I? The green runes clash with all the other color choices in the image IMO, and the odd ticks or slashes around the runes just look messy.
In the end none of it is badly done, KinG just stands out way too far due to all these details. I see the intent and it's not bad. It just strikes me as something that was simpler at one time and then you kept coming back to it and adding more and more.
Suggestions: Normalize the G in KinG. Emphasize the K and give it the same treatment as M in Mountain. Widen your parchment banner so you can shift Under The to the right, so you can shift King to the left and it's all still somewhat centrally aligned. Is the "Mountain" symbol in Mountain for the A really necessary? Makes your text look like wingdings. Again kind of an example to me of not being able to leave well enough alone. And the way the G does weird things just to accommodate a "lower order" of text....just way too much going on, too many mixed signals. It's a logo with a lot going on already compared to many game logos, and then it goes a couple steps further.
A wild suggestion: make King the same font as the rest, but make it like 3-d gold. That way you can get rid of the gold nuggets, one of which you're using to imply a dot for the I, even though the . is unnecessary because the whole word is done in block capital letters already. However maybe put a couple nuggets by the gems at the bottom just to keep the theme going. Maybe take the runes off of G and make them burnt into the wood in the back drop instead.
Bottomline for me: Decent overall work but "KinG" is an eyesore, and really makes me think mobile game when I see it.
