Hi spoonweaver, welcome to the community.
It depends a little bit on what exact style you want with the game, but I think it will help you a lot to check out some reference images of wasps
, especially queens, to give you an idea of how to depict them. At the moment it's a little hard to identify it as a wasp queen.
In terms of gameplay, you may want to make the boss more imposing by making it larger, and some part about it potent and dangerous, such as having it looming over the player with a stinger visible. Something like that, anyway.
Another thing is, what is it that the queen is on? Is that like, honeycomb? I'm not exactly an insect expert, but as far as I know wasps build their nests out of mud, with a hexagonal grid structure.
Hope that helps.
