Hello, hello.
To solidify the look of the game and make everything look like they fit together on-screen, I’ve looked for more art assets that looks consistent.
I decided to make due with what I have in hand, with that in mind. Here’s the updated and final look to my game.

My focus on the game, in terms of colour, would be Blue vs. Red.
Everything positive for the player will be coloured BLUE, while everything that would hinder the player would be coloured RED.
Quickly putting my images into GIFMaker.Me, I managed to obtain the look on how I my assets would look in-game, such as:


I plan to make certain assets rotate within Stencyl, (like the TARDIS, Daleks, Asteroids) I was going to manually rotate each image and save them multiple times but I stumbled upon this article and decide to experiment with it when I have more time.
Until the next update, see you later.
