I don't know how old you are tomster, but you definitely lack a lot of basic skills, such as simple perspective and shading. At the moment you are not very good at art at all, objectivly speaking. And I am not saying this to put you down or anything, everyone starts somewhere. From what I see in your picture you clearly need to start proper practise on your fundamentals.
What I suggest is drawing from life, leave pixelart or other digital media alone a bit and come back to it later after you are better in general.
Just take a sketchpad and a pencil and draw what you see, your family, pets, things in your room, outside, houses, trees, whatever you see. And do this alot.
And when you think you are more secure with form and perspective then you should try to take a stab at colour.
Imo pixelart is not a very good artform to start out with. It can be very beneficial when you are already intermediate or advanced at art because it gives you new ideas and approaches to different kinds of art.
Anyway keep it up and don't take things personal or as offensive, people here are very nice in general and all they wanna do is help you with their posts.
