use more fx other than smudging, your smudging is decent, but just smudging is hard unless your pro, which ive only seen a few people ever who can make something sick out of only smudge. if you like smudging, instead of using a stock, just paint in a color then smudge it around and repeat until you get something that looks nice. work on your coloring, i mean they dont suck but it needs some maps and levels.
good job
