Hi there!
I've seen so much great pixel art for many years, and it has always motivated me to try, but I never did. So.. I decided to finally give it a go. I'd like some advice, tips and critique. This was my first day, and it's also my first time posting, so go easy on me.

Here is a "Tower Defence" robot enemy with a hi-tech "pulsing" shield. (Self critique: I don't like my animation on the fire)
I've put my "save after save" so you can see my progress.
Turret Gun


Then after I did that, I made a front view version to keep consistency.

In the same session, I wanted to try something different.. I scribbled on the canvas and worked with what I could see.
And well.. I ended up seeing Kirby in a woolly hat, I found it funny, so I went with it. (Self critique: I think the hat's shape could make more sense)

After Kirby, I tried making a helmet for a knight, which didn't go so well, but I went through with it anyway.
Yes, I know the background looks terrible.
Knight Helm
I want to expand to environments as well as just simple character. If anyone can provide advice on expanding my work, please tell!
My work is clearly nothing compared to what inspires me, but what do you guys think of my work so far? Especially for day one! 
Thanks,
KrizppEdit:Just made a car. Name of the car? No clue.
Edit 2:I made a Tetris "mock up" with a total of 22 colours. It took me longer than it should have. I really love the "GAME OVER" font with the colour. I had a lot of fun with that one.
Edit 3:Had fun making a peaceful desert scene. Felt like it was too empty, ended up forcing it and now I have these terrible looking stairs. Still, I had fun.
