Hey there Schattenherz, welcome to the Guild! Looks good so far, but since you're asking for advice, here's my 2c. The blur that you've got going on the docks looks sort of funny. Perhaps you meant to give the impression that the docks were somewhat submerged, but nonetheless the faded blur still doesn't quiet look right. In addition, the grunginess to my eyes could be toned down a bit so as not to be too distracting. I'd also try adding some more texture and/or ripples to the river to give it a sense of depth. Otherwise this piece looks pretty good.

Cheers,
