Not very specific, but I may suggest finding something you like and emulating it to the best of your ability. By comparing where you want to go, you can find how to achieve it more easily as discrepancies are apparent. Then you can begin to nudge your work in a direction that you find valuable. Through working to emulate more and more closely aspects you appreciate, or things you find inspiring, whether from nature, photos, or stylistic and technical aspects throughout history, you will develop your own style. There are a lot of brilliant tutorials out there from talented artists willing to share techniques that you can apply to your own work in unique ways.
Your robot is looking cool. Remember one beauty of digital is that you can experiment broadly, even wildly and save many different versions. If you are in Photoshop you can experiment with all aspects of the brushes. Also painting textures on a separate layer then getting familiar with layer styles and blending options can give tons of great effects.
