Alright so this is something neat where you have shown some different elements to express different events here and some are good and some could be details more, but sofar i like what you have done here. So i am getting alot from this piece here, the rain the short circuits, the splashing of the rain aswell, it seems to all come together in a moment of relaxation for this character, there are some things i thought you could work on though such as, the short circutts could have a more glow to them and whatnot. And so here is the end of my review but i did enjoy the different elements and such that brought this piece out, some little changes as mentioned could improve on this piece.
~~THINGS TO IMPROVE ON~~
OK so through-out this review i have suggested a few areas and things that can be improved on the key points of improvment are below again for your use, and i enjoyed your work and hope you make more stuff like this. the short circiuts could have a more glow to them more lighted areas there and maybe evenputting some moon in the backround will give it more of a dark feel in the backround.
