Bomb Frog

There still some issues: design-wise and work-wise.
First of all, I don't suggest you work on a white canvas. If your sprite is supposed to be in, say, a forest in spring, the dominant colours would be green and brown; in that logic you should work on a similar colour so you get a good balance between the sprite and the background. That was work-wise.
Now design wise: you said this was a project. I guess if you are making a sprite then you are making a game. Design is one of the pillars of a game. It's you who's in charge of conveying a message through symbols to a player, and this must be done effectively if you want the player to fully understand the game logic. With this in mind there are two important elements in your object/character, a bomb and an on/off light. Both need to be highlighted. The eye is small and its colour change not that noticeable. The bomb must be visible, it must strike as dangerous. You can consider colour coding, saturation, contrast and borders to prioritise elements of your work.
The rest is superficially esthetic.
Here's an edit, which is done purely on those two points, it was not made to look technically impressive:
