Looks here and there I feel like the logo design doesn’t fit the hero genre feel consider removing that and making it more interesting something that’ll fit with the game icon, you could add some sort of effect or background so the text could fit. The logo you’ve made looks like something related to a (comic effect).
Include something on it or change the effect to resemble a certain theme of what your game will be you’ll need to experiment into adding different sorts of effects. If I were to suggest anything try finding a proper font the common use looks bland. Always consider using reference images to get little ideas to add to your own in-game thumbnail.
Otherwise it’s alright but there is still space for improvements that could be made to make it more appealing and interesting.
