Cool! I like the accented thin-line highlights in the art, it reminds me of the work by Zoe Persico. The layer blending is cool and gives it some nice texture, but is is to consistent throughout the foreground and background. To fix this you can make a mask on top of the texture blending layer and gradient it to exclude the far plane of the background to to sell it as being more distant. Also the lights on the axe are to selective of the area the affect, you should use a larger brush for those and separate the hard light from the softer light to prevent it from looking muddy.
Lastly if this is for the COTM you should fix the tags, you need to enter the tag legendaryaxe to be included in the competition
