This piece is really good! Lighting and colors are used to make contrast that sets the different elements apart to make a good composistion. The layout for the composistion is quiet simple ("circular" with focus in the middle) but works well. Most of the background blurry, if I were you I'd paint parts of the background closer in higher detail, then let that detail decrease further away. (Maybe add some more foreground elements like leaves, grass or rocks to indicate more debth?)

As for the character, I must say from looking at the gif process that I liked the initial design/look of the character a lot better than the final version. The sketched face looked a lot more natural and less goofy. The hair on the character (in my opinion) looks weird and a bit to puffy. Same as with the face I prefer the design of the hair from the sketch. His head also looks a little tall (maybe,,). I see that you blurred the hands to create debth, but it doesnt looks natural (elements close to the hand should also be blurred according to how close it is to the "camera"), therefore the upper part of the pole and the fish should be just as blurry as the hand.

One last thing I`d like to say is, what is the story behind him impaling a fish? Wouldnt it make more sense to have him impale a creature which is closer to desert/dry areas?

Overall this is a nice piece, but it has a few flaws that could easily be fixed. Im just going to mention some of the stuff you are doing well here (so that this review doesnt seem so negative): Ligthing, rendering(overall consistent), perspective and composition.

Im rating this piece according to what I have seen you draw/make before.

Oh wow, I really like this character and the expression you gave him, awesome job on the background!
