First, welcome. I just want to let you know, this place prides itself on making you a better artist, not just on the pixel end(however this is the bread and butter, here), but on all ends of the artistic spectrum. I bring this up, because you have asked not to make any critiques over the fire, because "you" like the way it looks. Thats fine. Just know that to the veteran pixel artist, those flames are extremely messy, and non-realistic. In my humble opinion, I don't think you can hide it's lack of artistic knowledge or skill behind a supposed "Style." So, I really do hope, that if you expect this piece to grow one ounce, you will consider detracting the statement: "Don't want comments on my fire." However, your piece, your property. Do as you will.
Second, as a devout follower of the pixel religion,

, it's damn near a sin to use the spray tool in any application, ESPECIALLY M.S. PAINT. Try looking up Google for some references on how mountains aren't just one shade or ramp of green through a warm scene such as this sun lit background. In fact, try noticing that not all things that are considered one color, are actually made up of multiple colors in real life. These "general" colors we associate things with, are only for basic memory, not truth. Almost a mirage. This will help you develop a respect to understanding just how important color selection with a palette really is. Also, Water is a reflective surface, which would imply that it reflects sunlight from where ever the source hits it. Don't forget, that water is an underestimated form of a live object. Captures of the ocean can often reflect many emotions, such as giant waves crashing over rocks, or flat oceans with a gentle sway to provide a form of calmness.
Finally the two most important things you will hear around here are Anatomy and perspective. To be honest, I don't think no one at this website has it down(including me, of course), so remember that we are all still trying to grasp these two important points. Now in this piece, the character's body is deformed almost to the point of a stick figure. The shading of him only consists of a gradient(another no-no). His feet are fatter than usual. His left arm is a bit fat towards the upper half, while his right arm is slimmer for some reason. He has NO ass, which make his legs align themselves perfectly with his sides.
I Agree with AdamAtomic, in that you should scrap this and start smaller to build up a firmer grasp of what really makes pixel art, pixel-art. With this media, it's more important to remember that in a technical sense( especially considering restrictions) less is more, and more is less. Hopefully you won't take these crits the wrong way, and can quite possibly grow from them. Like mentioned before hand, critiques are meant to help, whether they be harsh, or mild. This is world of the artists who take their work seriously. But I've went on too much already. If you do continue this piece, I'd at least try coming up with solid forms first, rather than details that make up forms.( and I'm pretty sure someone will come around later to correct some of my previous statements)
Good luck!
