First of all, nice work! The composition is really good, and the lighting is also really good. I’m also wondering, did you set this up to the golden rule? I haven’t placed it on top or anything, but it seems like it follows those guides fairly well.
Now, the biggest thing that sticks out to me, is the lack of Fresnel. You’ve managed to hide it fairly well with the lighting, but it still shows. I’m sure that if you add it, it will help bring a little extra life into this.
The rust on the blade looks very off, as does the lantern. It might need hand painting, specifically on the lantern, for it to work well. The handle on the ax also looks off.
The last thing, there isn’t enough interaction between the ax and the log. I’m guessing you just had it intersecting, but it would help a lot if the wood was chipping somewhat.
Another touch, could be to add some rust that dripped down on the logs.
I hope this was somewhat helpful.
