It's a start...
The first thing to notice is the colors. One simply cannot miss those. They are vibrant and strong. This hurts and helps your picture all at the same time. The things that stand out the most is the tiger, the belt, the bottom edge of the breastplate and pieces of the pillar in the background. These extra bright areas do help get your work noticed, but at the same time can pull the viewers eye away from the action, inevitably harming it.
Perspective is the next thing on the list. Cutting off the character at the ankles is already a big no-no when it comes to composition, but it also makes it hard for one to see if the character is in perspective with the background. This also separates the background from the characters, giving a disconnected feel.
Proportions on the elf are way off. Let us start with the hands. The hand by the face is much too small and seems disproportioned compared to the hand holding the bow. This also leads the arms. The left arm is much too large while the right arm is much too small.
The torso is long and thin, not only looking frail, but unbecoming of a warrior. The shoulders need to be wider to add a sense of power. The hips and shoulders are the same size which is typically considered inaccurate for males, especially a more athletic, stronger male. The right calf is huge while the left dampers too much. This makes him unbalanced, and coupled with the pose that is leaning too far back, makes him feel as if he is going to topple over any second.
The characters face, looks somewhat alright, although I do hate those ears. I have always hated the WoW design for elves, but that is between me and Blizzard, and I do not judge your piece on Blizzards faults. They eyes are a little larger, even if they are squinted, upon a full open they would be huge. Perhaps if you brought in the ends and tapered them a little they would not be so big
The overall design of the armor is too complicated without enough texturing and value. A simpler version that you build up too would have been more suitable.
Check your gear size as well; the arrow quiver is too small, even for a short bow, and the sword is only a little longer than a short sword. If this is what you were going for, then great. The bow I am starting to like, but it seems to taper really bad at the odd end. The top half looks really good an I like it, itâEUTMs just the end makes it seem unbalanced.
With this character I would like to have seen more âEUoeAdventuringâEU accessories, pouches, packs, perhaps a little dagger for mundane purposes, little stiff.
The tiger front paw looks like a wet noodle. ItâEUTMs limp and wavy looking like it lacks a bone.
There is a lot to fix in a piece like this, but at least you have taken one this far. That is an accomplishment of its own. I will look forward to another update from you in the future.
